There is a concept called Active Gravitational force and passive gravitational force. Active gravitational force accounts for the gravitational field strength of a massive object, whereas passive gravitational force accounts for how other objects gravitate in the gravitational field of the former one. The concept of acceleration due to gravity comes in the category of passive gravitational force. F= Ma or a= F/M . An interesting thing here is that in an active gravitational field the force acting on any mass is proportional to its mass and every time the ratio between force to mass taken, the result arrives is a constant, which is the acceleration due to gravity. Another important thing is that, when two bodies are gravitationally interacting, one with extreme larger mass (M) like earth and other with smaller mass(m) stone , the force between them is equal and opposite but due mass difference the stone will accelerate towards earth with constant acceleration of appreciable magnitude(roughly 9.8 ms^-2) whereas the acceleration of earth although constant towards the stone is so negligence to be detected. But between the sun (with extremely larger mass compared to earth) and earth the centripetal acceleration of earth towards the sun is of great magnitude. Simple formula: F= M A =ma, if F is constant then for M>>m, A

Apple Force ( formerly known gravitational force ) draws any object to its center ( and here, the surface of the earth is not center but the resting place with specific Apple Force power consumption ) at the same acceleration rate of 9.8 meter per second but gets squired when a falling mass holds up the Apple Force motion incrementally in same manner, reaching towards the distance to its center until gets obstructed or being at rest, to which the earth planet is being compacted. Either the earth or any object falling towards it doesn't attract each other rather they are compacted with specific Apple Force power.

I also have a que . light is electromagnetic waves it doesn't have colours in it .. then is light a mixture of waves whose wavelength are 380-450 nm ,,, 450-495 nm ,,,495-570 nm ,,,570-590 nm ,,,590-620 nm,,,620-750 nm .. as many teachers say apple appears red because it absorb all colours except red . but light do not have colours in it .. then it should absorb different waves that are in light ..but light is wave itself then how light has different waves in it
My name is jatin Kumar from faridabad haryana . I am preparing for neet 2025. Wave theory says that When a black body is heated then the intensity of flame increase not the color change. Particle theory says that intensity has no impact of temperature, it says that the freq increases and leads to the change in color. And in the ncert of class 11 chem . It is written - when an iron rod is heated in furnace it is initially dull red but as temp inc. it becomes bright or dark red . ( Wave theory) But in the next line it is written that the color change from red to blue. So my doubt is that here both theory are used and could not justify that intensity inc. or color change
Point 1: Understanding Mass and Inertia The mass of an object determines its inertia, which is its resistance to changes in motion. An object with a smaller mass requires less force to achieve a certain acceleration, while a more massive object needs a significantly greater force to attain the same acceleration. In simple terms, the heavier the object, the harder it is to start or stop its motion. Practical Example: Take two objects, like stones or books-one smaller and one larger (with noticeably higher mass than the first). Try pushing both. What do you feel? The object with higher mass requires more force to move, doesn’t it? That’s inertia in action. Point 2: Now, imagine you drop those two objects (one heavy and one light) from a certain height. What will happen to them due to Earth’s gravitational pull? Close your eyes and picture it. What do you see? (A) The heavier object will experience a stronger gravitational pull because of its larger mass. However, its greater mass will also make it resist acceleration more. (B) The lighter object, having less mass, will technically achieve higher acceleration. But since it has less mass, the gravitational pull on it will be weaker. Conclusion: As a result, both objects-regardless of their mass-will end up with the same acceleration due to gravity.
See potential means degree of unstability means if I have a spring which is fixed at one end and I have not done anything to that spring then it is in its normal or stable state or 0 potential but when I stretch it I disturbed from its normal state , at that point it has some degree of unstability and that is called as potential.

@@mitrayusinha9810 There are free electrons in the whole wire [ assuming the wire to be a good conductor] and since as you said it’s positively charged in one half and negatively charged in second half then there would be an electric field in the whole wire from positive part to negative part and electrons all over the wire will start experiencing the electric field as soon as electric field is established [ Here As soon as you get your wire positively and negatively charged , at that instant only electric field is established and electrons all over the wire start experiencing the force].

Helicopter Location on Earth. User If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates ? ChatGPT Yes, if a helicopter remains stationary at a fixed location on the surface of the Earth for 20 hours, it will change its location due to the rotation of the Earth. The Earth completes one rotation on its axis in approximately 24 hours. Therefore, during the 20 hours the helicopter remains stationary, the Earth rotates by approximately 20/24 or 0.833 degrees. This means that the location of the helicopter on the Earth's surface will have changed by 0.833 degrees due to the Earth's rotation. The exact distance the helicopter has moved depends on its location and the distance from the equator. The distance covered by the helicopter can be calculated using the formula: distance = (angle in degrees) x (pi/180) x (radius of the Earth) Assuming the helicopter is at the equator, which has a radius of approximately 6,371 kilometers, and the change in position due to the Earth's rotation is 0.833 degrees, the distance covered by the helicopter in 20 hours would be approximately: distance = (0.833) x (pi/180) x (6,371) = 147.8 kilometers Therefore, after 20 hours, the helicopter would have moved approximately 147.8 kilometers due to the Earth's rotation. User If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates? Which country will it be ? ChatGPT If a helicopter remains stationary at a fixed location in India for 20 hours, it will change its location due to the rotation of the Earth, as explained in my previous answer. However, the helicopter will still be in India after 20 hours, just in a slightly different location. The change in the helicopter's position due to the Earth's rotation is determined by the latitude and longitude of its initial position. Assuming the helicopter is initially located at a fixed point on the ground in India, its new position after 20 hours will still be in India, just shifted slightly due to the Earth's rotation. The exact location within India where the helicopter will end up after 20 hours depends on its initial position, as well as the latitude and longitude of that position. The change in position due to the Earth's rotation will be different for different locations within India. However, it is safe to say that the helicopter will still be within the borders of India after 20 hours, just in a slightly different location
why gravitational constant has dimension. It just a number… force has dimensional formula as MLT-2 which mean it depends on mass length time .. but gravitational constant is just constant it does not depend on any .. Then how G has dimension
Agar,Mass pe dependent vi ho,tab vi earth and a small ball (Let-1Kg)per same force act hoga.because of very huge mass of earth 🌎 its acceleration is a=F/M=1.640939086×10^-24 m/s2 which tence to Zero.but for a ball 🏀 acceleration is a=F(same)/m(small)=9.8 m/s2 .this acceleration is very very high respect to earth.

If somehow the acceleration of both object and earth are the same . We know the force acting on both is also the same (Newton's 3rd Law ) . Therefore the mass of both the objects must have to be same to satisfy F=ma (Newton's 2nd Law ) which is not never never possible. Hence , this can be proved by contradiction method

So my doubt is that here both theory are used and could not justify that intensity inc. or color change
That is why we say, half knowledge is even more dangerous . Whenever we know any result of nature, underlined conditions must be known very well..
Such a humble person❤😍
We can also understand this by examining the equation of gravitational field strength i.e. acceleration due to gravity...
You are my inspiration sir ❤
Sir can you tell us why does the acceleration due to gravity not depend upon the mass of the object ... Not mathematically... But practically
Point 1: Understanding Mass and Inertia
The mass of an object determines its inertia, which is its resistance to changes in motion. An object with a smaller mass requires less force to achieve a certain acceleration, while a more massive object needs a significantly greater force to attain the same acceleration. In simple terms, the heavier the object, the harder it is to start or stop its motion.

Take two objects, like stones or books-one smaller and one larger (with noticeably higher mass than the first). Try pushing both. What do you feel? The object with higher mass requires more force to move, doesn’t it? That’s inertia in action.
Point 2:
Now, imagine you drop those two objects (one heavy and one light) from a certain height. What will happen to them due to Earth’s gravitational pull? Close your eyes and picture it. What do you see?
(A) The heavier object will experience a stronger gravitational pull because of its larger mass. However, its greater mass will also make it resist acceleration more.
(B) The lighter object, having less mass, will technically achieve higher acceleration. But since it has less mass, the gravitational pull on it will be weaker.
Conclusion:
As a result, both objects-regardless of their mass-will end up with the same acceleration due to gravity.

N.B. - Does energy flow through wire ? If I have a wire 12 lakh km long (6 km +ve , 6 km -ve ) , then will it take 4 sec to light a bulb or just instantly?
This question was actually answered by veritasium in a series of two videos. You will get the best conceptual understanding there.

Instantly drift speed
@@donno9984 can you explain
@@mitrayusinha9810 There are free electrons in the whole wire [ assuming the wire to be a good conductor] and since as you said it’s positively charged in one half and negatively charged in second half then there would be an electric field in the whole wire from positive part to negative part and electrons all over the wire will start experiencing the electric field as soon as electric field is established [ Here As soon as you get your wire positively and negatively charged , at that instant only electric field is established and electrons all over the wire start experiencing the force]. So yes you can say it’s takes negligible time to light up the bulb
Sir the are bubbles formed in bottle in landscape view(not in portrait view) if they are formed in air they should be formed in both the cases
Sir this is my QUESTION:-
" AS WE know earth is moving round
So if we flied helicupter above the earth surface at any certain height in India and fixed its positioning(like it's not moving it's just at a place above " ) then if continued this process amd kept our helicopter stationary (*like sometime birds are a same place neither they are moving upward,downward,back nor forth*)
Will after 24 hours(* one complete rotation of earth) that same helicopter flewed in India be in America (* or any other places or countries)
**ASSUMPTIONS IS** A earth is moving but helicopter isn't so it has to be sky but the ground level has to be changed *)
Please reply sir..
Or any of you who understood my question and has answers
Baaki sir ki smile achi lagtibhai 😊❤❤❤❤
Bhai wo india ke usse fix part pe hi rhega 24h ke baad bhi
Helicopter Location on Earth.
User
If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates ?
ChatGPT
Yes, if a helicopter remains stationary at a fixed location on the surface of the Earth for 20 hours, it will change its location due to the rotation of the Earth.
The Earth completes one rotation on its axis in approximately 24 hours. Therefore, during the 20 hours the helicopter remains stationary, the Earth rotates by approximately 20/24 or 0.833 degrees. This means that the location of the helicopter on the Earth's surface will have changed by 0.833 degrees due to the Earth's rotation.
The exact distance the helicopter has moved depends on its location and the distance from the equator. The distance covered by the helicopter can be calculated using the formula:
distance = (angle in degrees) x (pi/180) x (radius of the Earth)
Assuming the helicopter is at the equator, which has a radius of approximately 6,371 kilometers, and the change in position due to the Earth's rotation is 0.833 degrees, the distance covered by the helicopter in 20 hours would be approximately:
distance = (0.833) x (pi/180) x (6,371) = 147.8 kilometers
Therefore, after 20 hours, the helicopter would have moved approximately 147.8 kilometers due to the Earth's rotation.

If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates? Which country will it be ?
ChatGPT
If a helicopter remains stationary at a fixed location in India for 20 hours, it will change its location due to the rotation of the Earth, as explained in my previous answer. However, the helicopter will still be in India after 20 hours, just in a slightly different location.
The change in the helicopter's position due to the Earth's rotation is determined by the latitude and longitude of its initial position. Assuming the helicopter is initially located at a fixed point on the ground in India, its new position after 20 hours will still be in India, just shifted slightly due to the Earth's rotation.
The exact location within India where the helicopter will end up after 20 hours depends on its initial position, as well as the latitude and longitude of that position. The change in position due to the Earth's rotation will be different for different locations within India. However, it is safe to say that the helicopter will still be within the borders of India after 20 hours, just in a slightly different location
@@Mitochondria312 Thank you brother!!!
Science leads to sprituality
why gravitational constant has dimension. It just a number…
force has dimensional formula as MLT-2 which mean it depends on mass length time .. but gravitational constant is just constant it does not depend on any .. Then how G has dimension
Sir am your big fan ❤❤
Thankyou sir!😀
Agar,Mass pe dependent vi ho,tab vi earth and a small ball (Let-1Kg)per same force act hoga.because of very huge mass of earth 🌎 its acceleration is a=F/M=1.640939086×10^-24 m/s2 which tence to Zero.but for a ball 🏀 acceleration is a=F(same)/m(small)=9.8 m/s2 .this acceleration is very very high respect to earth.
Sir I don't know whether my doubt is Dumb or not but I am asking still. Sir, work done in moving a charge from centre of a spherical shell is 0. Since V=W/q --> V=0 at centre according to formula but charge's potential at centre is same as that of its surface. V---> Potential 'just for info'
V is not W/q , its Energy/q and W= change in Energy so if W=0 means change in energy is 0 means energy and potential is constant.
@@tarunsuman1676 sorry did'nt get your point
Sir a question floating in my mind we know rate of flow charge known as current so how current two type AC and DC
Excellent Sir ❤❤
Hello sir , I have a question , how fair is to consider mass is variant by relativity concept. Can we also say mass is dependent on frame of reference.. sir i will be highly obliged if you will guide me for this..
Bro mass is fame dependent if u go speed of light then mass changed
@@resonancegaming7404 not necessarily speed of light
Mass is the measure of inertia. It should not change while changing frame of reference.
@@mitrayusinha9810 that’s rest mass, not relativistic mass
@@aman_sp03 You are right. Thanks there .
Sir my name is anshu Bhawsar, I am from mandsaur Madhyapradesh,
My Question is that as we know that there are infinite number of possible orbits (assuming circular orbits) Of a fixed radii is possible around a heavier objects in space but that shows means there are infinite number of possibilities to create whole in space time fabric but black whole creates only One agretion disk how it is possible
sir mereko ek question hai jaab haam ek sphere metal ball ko heat karke red hot iron karthe hai aur usko ek ice cube pe dalthe hai vo sphere ghumne lagtha hai kya hum isko work done , heat absorbed , Thermodynamics ke madad se explain kar sakthe hai ki vo ball kithne temperature par kithne tej ghumega ya kithne dair taak ghume ga can we link the concept yo work done and thermodynamics
Karta hai mass par depend but planet ke mass par
Gravitational acceleration mass pe dependent krta hai agr mass bahot jyada ho to, like agr earth pe earth ke mass ke half maas ka object gir rha ho
light is electromagnetic waves it doesn't have colours in it .. then is light a mixture of waves whose wavelength are 380-450 nm ,,, 450-495 nm ,,,495-570 nm ,,,570-590 nm ,,,590-620 nm,,,620-750 nm .. as many teachers say apple appears red because it absorb all colours except red . but light do not have colours in it .. then it should absorb different waves that are in light ..but light is wave itself then how light has different waves in it
Bro apple have red pigments which make it appear red that would the reason i think!
Thank you so much Sir
Sir I have a question that in the areas where temperature is in (-ve) the lake freezes upto some extent why it is not frozen completely we can easily find water if we dig there ??
Class 10 icse
If somehow the acceleration of both object and earth are the same . We know the force acting on both is also the same (Newton's 3rd Law ) . Therefore the mass of both the objects must have to be same to satisfy F=ma (Newton's 2nd Law ) which is not never never possible. Hence , this can be proved by contradiction method
Sir please tell me why we use electrostatic potential not electro variable potential
Sir please ya batao 10/2 which is not coprime and √2 which we prove coprime in ist case we say its rational in second case we say it is irrational how ?????
Please tell me if any one know
Mere sir bhi kaha karte hai ki kisi formula ko yaad rakhne se jyada jaruri uski conditions ko yaad rakhna hota hai
GMm/R2 hota hai to simple hai a is Gm/R2 ab since m is small acceleration is small still wo Earth ka mass pe depend nahi kar rha Sahi hai!
ya great , i also do this at iit this year'
Sir my question to you is that why the universal gravitational constant is not same at dark energy
Sir please explain skin effect
Sir is on the way to become Newton 😃
The doubt is that If we defference temperature in degree Celsius and convert in the Kelvin and got the answer but if we convert the temperature before difference and subtract then convert into degree Celsius and the answer both answer are different. Why?
