I read this in HC Verma and was confused about inertial frames and then I searched (Inertial frames) on TH-cam . Guess what , The author of the book came to clear my doubts. 😅
I’m 31 now, and it’s now that I’m finding the right places to resolve my doubts. I had read Verma sir’s books throughout my senior school days but I never had an avenue to pick his brains or directly learn from him and channels like 3Blue1Brown. But now I have a newfound love for Physics and Mathematics all over again. I guess I was born too early. 😂 But I guess, I also hated to learn back then because we were learning to chase exam after exam, and not to actually understand these very concepts in an applied manner. It’s rather now that I don’t have to learn to quench the dogma of someone evaluating my knowledge that I have this rekindled love for this beautiful subject. We’re generations of victims of a flawed education system.
Thanks. From this I was able to determine my bedroom is inertial. My laundry is not accelerating toward the washroom and I'm definitely not about to apply a force to it.
Thank you for suggesting and setting up a criteria for judging weather a frame of reference is inertial or non inertial. Most teachers I know are not so clear on this subject.
Some statements by HC Verma Sir in this video are wrong, but this is still better than what is there in the book. 1. First improvement can be made by saying "any particle at any time" instead of "a particle" when defining Inertial Frame. HCV: If you look at A PARTICLE with no net force acting on the particle, and if from a frame of reference F if the particle has no acceleration, then the frame is inertial Better: If you look at ANY PARTICLE at ANY TIME with no net force acting on the particle, and if from a frame of reference F if the particle has no acceleration, then the frame is inertial 2. Second improvement needs to be made to incorporate rotational frames. While the above will NEVER give you a false positive for inertial frame, it may still give you a false impression for the test of inertial frame. The way relative motion is defined in HCV Book and most other books, it gives an impression that if a frame F1 is non-inertial wrt an inertial frame F0, then F1 has an acceleration wrt F0, say a1(vector). Students then wrongly imply that a particle with no acceleration wrt F0 would have an acceleration -a1(vector) wrt F1. Well, the particle may still have 0 acceleration wrt F1 as well if F1 is not translating but purely rotating wrt F0 and the particle is on its axis of rotation.
@@chathuminiudawatta4612 Let F0 be the inertial frame (say something like your room with a ceiling fan). Let the fan be rotating uniformly wrt F0. Let this fan be the reference frame F1. Let there be a ball just below the axis of rotation of F1. Now, F1 (ceiling fan) is a non-inertial frame of reference and ball has no acceleration in either F0 or F1.
No we don't need another frame to determine if s & s' is inertial or not. Sir just gave an example to explain that it's not relative, don't take it in wrong meaning. Either a frame is inertial or non inertial, there's no relativity between them.
I think if it mainly depends on where we are seeing if we are having same accelerated then it will be inertial to us and if some other guy is seeing us who is at a rest then he finds us at non inertial frame
How to know if a particle has outer force acting in it or not? Like if its non-contact force, only way we say its there is based on acceleration right?
That means if I'm on earth watching a bottle kept on ground , in my perspective the bottle is at rest but we both,me and bottle are moving along with earth with a equal acceleration.
Let's take a block slipping on a wedge. Everything is frictionless. So the wedge accelerates backwards. So does the block experience a pseudo force towards right? Why? I have problem in grasping this thing. Any help would be appreciated.
Well I think your question answers you. Just ask that why is that wedge moving, because of the force component when the block is accelerated downwards. So it is rather an action reaction couple not pseudo as far as I see
Dear ideal sir, Still the confusion remains the same.as u ended that the 3rd frame with respect to which there two frames are being obseved can be non inertial, then that 3rd frame is accelerating with acceleration 'a' then in that case will these frames s and s' be inertial or not with respect to that frame?
If f is zero then acceleration is zero and if f is non zero then acceleration is not zero,does it still inertial frame but acceleration is zero in inertial frame so how does it follows Newton's law and at the same time it is non accelerating.I m confused if you know the answer please reply
@@jalilkhan6251 to understand a frame of refrence what i usually do is i imagine if my one eye is in the place of the point particle from which you want to observe...the world seen by that eye is the frame of refrence ..yes it is 3d.....for example if i want to talk about the frame of refrence of a 'fired' bullet..i think i am the bullet...then i would be at rest and the whole world would go backward...if the bullet was accelerated...then every thing in this world ( frame of refrence of bullet) would experience a pseudo force in the opposite direction ( except the bullet ..it is on rest)..and so on ..if there is some irregular shaped body..i would put my eye in the place of its centre of mass and then i will imagine the world from that perspective...but for imagining something from the ground frame i would just think of my self as a spectator observing the events happening standing on the ground...so yeah BE the thing from which you want to observer the frame( the world from that things perspective...hope this was helpful
But how would someone know if the net force on that particle 3:29 is 0 from that frame of reference? If we know that there is an acceleration, then the only statement we can certainly make is that there is a net force acting on that particle.
Sir ,I have a question regarding the above video. Sir a body in which the acceleration is acting how can it be possible that the net force acting on the body is 0 as we know that F=ma????
Bro that's because in a non inertial frame newtons laws are not applicable... So F=ma becomes null and void in a non inertial frame... In that case we are introduced with the concept of pseudo forces
Assume you are in car and your car is accelerating at some 5m/s^2 and then you open the window and see an object the object will seem to be coming towards you at the rate of 5 meters per second and you know that the net force on the object is zero so as to solve the problems we assume it is accelerated by some force which has magnitude of (acceleration of observer times mass of object), If you think it about carefully it makes sense.
Or you can assume that may be the frame from which u are seeing the object may be not at rest so actually the f=ma for that particle may be zero but u may see it is moving (may be sometimes true that the particle is really accelerating) so we can say that our frame is interial if we see it not accelerating or may be particle may be accelerating u never know ! Ever thing is relative u just need the right way😃✌ hope this helps
ChatGPT Yes, if two frames of reference are accelerated with the same acceleration, they can be considered as inertial frames of reference, at least for the duration of their synchronized acceleration. An inertial frame of reference is a frame in which Newton's first law of motion holds true. Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force. In other words, there is no acceleration (change in velocity) in an inertial frame unless an external force is applied. When two frames of reference are accelerated together with the same acceleration, the relative motion between the two frames remains constant during the acceleration period. This means that any observer in one frame of reference will not be able to detect the acceleration of their own frame relative to the other frame. Since no relative acceleration is perceived, both frames can be considered as inertial frames with respect to each other during the period of synchronized acceleration. However, it's important to note that if the acceleration of one frame relative to the other changes, or if there are non-inertial forces present within either of the frames, then they would no longer be considered inertial frames. Inertial frames are only valid in the absence of external forces or accelerations.
He is a great person and he wrote the book H.C VERMA. In that book we can find excellent problems and theory . By reading the theory and by doing the problems we can get a grip about the topic. The book is excellent.
Why a ball placed in a frictionless surface in a car moves with same velocity when the car is accelerated. What is the relationship between the ball and frictionless surface for moving the same velocity
If the contact surface is frictionless the ball doesn't move with same velocity it is the friction force which opposes any form of relative motion between the two surfaces in contact
noif the surface is actually frictionless. it will not move with the same velocity...from car's frame( for example from drivers seat)..you would see the ball going backwards with the same velocity as that of your car...in case of car accelerating ..a pseudo force would work on the ball from the car's frame which would accelrate the ball in backward direction
Sir why force is not depend on frame of reference. When we see a duster which is in rest the duster has net force 0 and when we see the same Duster on moving we see that it has an acceleration so how we can say that force is independent of frame of reference?
"If u love physics then look at the black board,but if u do not have any idea about physics then just stare to his eyes and his loveable innocent smile.obviously u will fall in love with H C Verma and in Physics.." 🇧🇩🇧🇩
These are the same frame . If t1=t2 , if t1 =| t2 v=u+at .. if those events started at different times they are non inertial to each other. If that's not the case if all have same event of starting All are in same frame what we called for s the s' is absolute frame . . But if the observation is outside ..it non inertial ..
Sir , I have a question that How it happen that a force is 0N but it has acceleration . Sir, if you say mass is 0 then the particle which has no mass then it is not a matter so how it's have acceleration
Sir, in the timing 04:07 it has been Mentioned that if the net force acting on the body is zero and the acceleration is non zero then the body is said to be non inertial frame. But my question is that if the net force on a body is zero, how can the acceleration on that body be zero? we know : F=m.a so, 0= m.a since m can't be zero therefore a= 0
SIR IF IN CIRCULAR MOTION A PARTICLE GOES FROM POSITION 1 TO POSITION 2 WHILE THE POSITION 1 AND POSITION 2 ARE OPPOSITE TO EACH OTHER ON THE CIRCUMFERENCE OF THE CIRCLE AND THE FORCE IS ACTING TANGENTIALLY AT EACH POINT IN THE PARTICLES MOTION AND HAVE THE SAME MAGNITUDE 10N THEN WHAT IS THE WORD DONE BY THAT FORC3
Sir if we have two frames moving with a constant acceleration @ and with respect to them there is one body moving with the same acceleration @ ,then will the frames be inertial or non inertial?
@hcverma2928, If a particle is falling from 10th floor and is weightless, don't you think he is in inertial frame of reference. According to General relativity it's the experience which matters and is following a straight line.
Everything in this universe is moving with some acceleration... There is nothing as inertial frame if you consider every motions.. But as you change the perspective and put a bigger entity at rest... Motion of other bodies smaller than it can be described and hence we could say tha it is an initial or non inertial frame... So it depends on the *universe* you chose
@@pankajchauhan1348 Are you joker?! Force is independent of frame. So Newton second law is independent of Frame except pseudo force which is dependent on non inertial frame.
@@PankajKaswan007 man u better read HC verma's concept of physics , he said F=ma is just valid in inertial frame so in non inertial frame we have to apply a pseudo force to make it valid
It completely depends on frame wrt which the particle is accelerating, for example if you are inside an accelerating car and see some building, you find that the building is accelerating backwards from your frame. The net force on the building is zero, yet it is accelerating in your frame, so your frame is non-inertial.
Last line that verma sir said is the exact what the students asked him...So what is the answer actually...wrt a non inertial frame(A), what ll be the type of reference frame(B)if B is non inertial wrt to a inertial frame(C)..??? Plzz answer...Is it always the inertial frame that we have to view any non imertial frame from???
Sir, I can know if the acceleration of a particle is 0 but how do I be sure that the force on it is also 0 , to know if my frame is inertial or non- inertial?
If acceleration of any body is 0, then it means force is obviously 0 because f=ma(Newton's 2nd law) Then inertial frame is that which is not undergoing acceleration means acceleration is 0, such as rectilinear motion, object is at rest. Since acceleration is 0,frame is inertial. Hope u get it...
Finding an External unbalanced force existing applied on to a frame is not the sure diagnostic to assign a frame to be an inertial or non inertial. For assigning a frame to be non inertial it is enough and all enough to know if the frame is accelerated ie; the frame is not maintaining its state of motion the same along the same straight line at every instant always and all the time. One thing more important and highly important is that acceleration doesn't need any reference frame for any comparison. When bodies do not execute equal displacement in all the equal intervals of time (instants of time), whether, the time inerval may be very very small the bodies are held to be in acceleration, obviously non inertial.
In hc verma book, it is fully opposite the way the teacher is teaching now. The inertial and non inertial is justified by the relative with other point is said in book but sir told that it is not the case
f=0 , a= non zero. this is the situation when particle is not accelerated but the frame itself is accelerated. so F on particle is zerro. but accceleration if you measure you will say it is non zero. with some magical pseudo force( that which is not even there in reality) on it.
Sir then are the concept of inertial frames applied to quantum mechs as you said the particle shoulf not be accelerated but acc to heisenburg uncertainity how is it possible that when we se a quantum particle it's not accelerated. Since you have mentioned that quantum and classical physics are different but just a question ?

Yes, if two frames of reference are accelerated with the same acceleration, they can be considered as inertial frames of reference, at least for the duration of their synchronized acceleration.
An inertial frame of reference is a frame in which Newton's first law of motion holds true. Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force. In other words, there is no acceleration (change in velocity) in an inertial frame unless an external force is applied.
When two frames of reference are accelerated together with the same acceleration, the relative motion between the two frames remains constant during the acceleration period. This means that any observer in one frame of reference will not be able to detect the acceleration of their own frame relative to the other frame. Since no relative acceleration is perceived, both frames can be considered as inertial frames with respect to each other during the period of synchronized acceleration.
However, it's important to note that if the acceleration of one frame relative to the other changes, or if there are non-inertial forces present within either of the frames, then they would no longer be considered inertial frames. Inertial frames are only valid in the absence of external forces or accelerations.

@@ShivamSrma true
@@ShivamSrma I still watch his videos on quantum mechanics helpful for 1st semester as well
@@satyajeetiitbombay5532 Yes, I would still study his books and Lectures even when I will be employed. ✌️🤭
Sir how we will write second law of motion w.r.t non inertial frame... with vectors and pseudo force
I am starting a pure research institute like xerox and paarc but will make it profitable.Donate on phonepe 7259293140.
Your explanation is mind blowing
Thanks you sir u are just amazing sir I understand the concept in my first try
Really really thank u sir
THANK U SIR TO CLEAR BASIC DOUBTS
i m ur big fan sir. really u shoulg be called THE GEAT TEACHER
@hcverma2928, If a particle is falling from 10th floor and is weightless, don't you think he is in inertial frame of reference.
According to General relativity it's the experience which matters and is following a straight line.
Thank you so much sir for this video cleared my doubt😊
Sir , where can we find non inertial or pure inertial reference frames ?
Everything in this universe is moving with some acceleration... There is nothing as inertial frame if you consider every motions..
But as you change the perspective and put a bigger entity at rest... Motion of other bodies smaller than it can be described and hence we could say tha it is an initial or non inertial frame...
So it depends on the *universe* you chose
if acceleration is not equal to 0 then; could the force on the particle be F=ma
No bcz all laws are in valid in non inertial
You apply pseudo force to balance this
@@pankajchauhan1348 Are you joker?! Force is independent of frame. So Newton second law is independent of Frame except pseudo force which is dependent on non inertial frame.
Yes! f=ma will be applied. If Acceleration (Actually or Pseudo in both cases) is not zero.
@@PankajKaswan007 man u better read HC verma's concept of physics , he said F=ma is just valid in inertial frame so in non inertial frame we have to apply a pseudo force to make it valid
Sir you are the best concept explainer
Thank you sir for such beautiful concept.....
Thanks for this video sir..
Perfect !! Just whats needed ! Crisp !
Happy gurupurnima sir
Sir kya kis cheez ka maas km ho skta hai nuclear physics me.
Well at least the teacher agrees with me that earth is an accelerated frame and "free falling" is an inertial frame.
Sir, kindly explain how can a particle accelerate when external F=0? Thank you
It completely depends on frame wrt which the particle is accelerating, for example if you are inside an accelerating car and see some building, you find that the building is accelerating backwards from your frame. The net force on the building is zero, yet it is accelerating in your frame, so your frame is non-inertial.
@@sashankbajaru77 Thanks a lot
@@crcracing-v4z yeah the car frame
Sir please make a video to explain pseudo force
Last line that verma sir said is the exact what the students asked him...So what is the answer actually...wrt a non inertial frame(A), what ll be the type of reference frame(B)if B is non inertial wrt to a inertial frame(C)..???
Plzz answer...Is it always the inertial frame that we have to view any non imertial frame from???
Sir, I can know if the acceleration of a particle is 0 but how do I be sure that the force on it is also 0 , to know if my frame is inertial or non- inertial?
If acceleration of any body is 0, then it means force is obviously 0 because f=ma(Newton's 2nd law)
Then inertial frame is that which is not undergoing acceleration means acceleration is 0, such as rectilinear motion, object is at rest.
Since acceleration is 0,frame is inertial. Hope u get it...
Finding an External unbalanced force existing applied on to a frame is not the sure diagnostic to assign a frame to be an inertial or non inertial. For assigning a frame to be non inertial it is enough and all enough to know if the frame is accelerated ie; the frame is not maintaining its state of motion the same along the same straight line at every instant always and all the time. One thing more important and highly important is that acceleration doesn't need any reference frame for any comparison. When bodies do not execute equal displacement in all the equal intervals of time (instants of time), whether, the time inerval may be very very small the bodies are held to be in acceleration, obviously non inertial.
thank you for the great explanation.
The great padmasree HC verma ,"The DADU of Indian Physics"🔥🔥🔥
In hc verma book, it is fully opposite the way the teacher is teaching now. The inertial and non inertial is justified by the relative with other point is said in book but sir told that it is not the case
How it's possible.. for non zero acceleration net force will become zero?? What kind of situation it is ??
f=0 , a= non zero. this is the situation when particle is not accelerated but the frame itself is accelerated. so F on particle is zerro. but accceleration if you measure you will say it is non zero. with some magical pseudo force( that which is not even there in reality) on it.
Sir u r really great sir
Sir then are the concept of inertial frames applied to quantum mechs as you said the particle shoulf not be accelerated but acc to heisenburg uncertainity how is it possible that when we se a quantum particle it's not accelerated. Since you have mentioned that quantum and classical physics are different but just a question ?
