I have never seen such an immensely impressive and simple explanation on the nature of a projectile motion. Projectile motion made simple. I was having a hard time to understand why we have zero horizontal acceleration during a projectile motion. Now, I got it.
I'm physics Student and i teach physics from 3 year the projectile motion is very interesting topic in motion this video very helpful and effective also for me.
Please make more physics videoes like this, you are the only one who knows how to teach properly that makes me understand, both your calm and clear voice along your animated videos should go viral.
This is only an introduction to gunnery. One might consider density of air, fog/rain. Temperature of gun powder (output speed). Fit between grenade and barrel. (Output speed) Deflection due to spin of grenade. Grenade precision movement ++ Anyway, a fine start to the subject.
0:30 THEY both will land at the same time because Time taken at the y-axis or ascent = time taken at the descent and here time taken by the ball when dropped is the time taken at the y-axis or time of ascent which is equal to time of descent.
Starting at 1:00 there is an error as it assume drag doesn't exist. The moment the ball leaves the hand, the speed of the ball is the fastest, but also the drag of the ball is also highest. Drag increases according to the inverse square law, so will begin to slow down much quicker in the first second than the second and so on. So the horizontal motion does not remain constant all the way through the arc.
I remember the time when I was in class 11..I tried remembering all the formulas to solve the numericals but always made some error.. That time byjus used to give free minutes for new members who register on thier app.There I learnt this concept very well let it be normal or inclined or moving plateform projectile.
Great representation of this physics fact! All other things (like wind and air density) kept equal, a bullet fired *horizontally* will hit the ground at the same time as a bullet DROPPED at exactly the same time the gun was fired…….just much farther away down range!
The whole thing will drammatically change if air friction will be added. Presented explanation is valid in vaccum or in case of low projectile velocities. I case of air present there's a need to calculate the force of air resistance with each simulation step. It depends on projectile velocity, so shooting flat with high horizontal velocity will not be an advantage due the fact initial speed will be rapidely lost due to friction. In this case higher angles will be better.
Depends on what level is being taught to. The projectile slows as the time of flight increases. It has been assumed that the initial and final velocities are the same. I have been told that the maximum distance is achieved by using an angle of 60° so that it spends more time travelling at the slowed velocity of terminal flight.
45° is close enough for Government work. The first is called a ranging shot, then corrections are made by a forward observer. There are many other factors involved. Altitude, temperatures, wind speed, Coriolis effect (for LONG range), muzzle velocity, ballistic coefficient of the projectile, etc. Weapons today utilize computers to do the calculations to aim and hit a target at maximum range within a few meters. The Abrams tank can do it even while moving at maximum speed.
Sir, can you make a video on nernst theory? It says, "According to Nernst theory, electrode potential is the potential difference between metal and ionic layer around it at equilibrium, i.e., the potential across the electric doubled layer."
Schools: Teaches things for cramming and acing exams, destroying the concept of learning. Sabins: Interestingly teaches things, spreading knowledge in a way where we ACTUALLY learn.
Both stones do not land at the same time. The one thrown horizontally has a longer path, so air friction will slow it down a tiny bit more, increasing the time it takes to get to the water. If you said the 2 stones will hit the water at aproximately the same time you would have been correct. Air friction also makes 60 degrees the optimal angle for greatest range on large cannon projectiles.
Apparently you've never been around any weapons that fire bullets. Because this may be true in the absence of atmosphere. The longest range is somewhere between 33 and a half to 35 degrees of inclination. But that's in actual practice on our Earth.
this means that you can throw a ball horizontally with enough initial velocity that it orbits the world before returning and landing behind you at your feet, and drop a ball from your other hand and from the same height as the throw, and they will still hit the ground at the same time.
yes correct. it is obvious if a ball has horizontal velocity ,it will follow projectile path before hitting ground. it will spend more time in air as compared to ball with zero horizontal velocity. spending more time in air means delay in hitting ground.
This video said "The maximum range happen for a 45° angle". That's fals EXEPT if they add "Without taking count of the air friction. Since the represent a cannon that's not true in that exemple
Both the objects will not reach the ground at the same time ❗ Since, both the objects are under the influence of same gravitational acceleration. Also the horizontal motion of the thrown object, doesn't have any affect on its vertical motion. The vertical velocity both the objects are same at any given time during their fall and both the objects falls from the same height. The object with the horizontal motion needs to travel a greater distance compared to the other object . Soo, it takes a slightly longer time to reach the ground. In reality, the difference is very small, and both objects appear to reach the ground simultaneously.
The maximum range for a projectile is achieved when the starting angle and the end angle is at 90 degrees to each other. That angle is not always 45 degrees of course. It depends on the height difference of the start and end.
This describes the gravitational component of projectile motion only. The effects of wind drag have a dramatic influence on the trajectory of high velocity projectiles… this should have at least been mentioned in this video so as to not be misleading.
It's oversimplified. May be truth for vacuum or very low projectile speeds. In real life (and high speeds) atmosphere resistance must be taken into account. At extreme speeds and heights you should also consider facts, that atmosphere density is different at various heights, and earth is not plain.
No hand thrown object describes a parabola. A parabola describes a uniform curve. Any hand thrown object describes a gentle curve at first. Later in its flight the arc becomes more pronounced so the arc is not uniform as in a parabola.
both stone hv 0 vertical velocity ok . both pulled at 9.8 m/ sec.sec downwards. 2nd stone has some horizontal velocity which converts its motion in projectile motion. 2nd stone spent more time in air as compared to 1st stone due to its projectile motion. \how it hits water at same time !
This something schools can't teach properly. Sabin has always been helpful.
45 deg is just common sense but there's none of that today... TH-cam videos to the rescue
Absolutely right 👍

This is the most clearest explanation for projectile motion concepts that I have found on youtube.Thanks sir...We need more ❤️🔥
A whole generation will learn with your videos, LESICS and SABINS. Thanks for helping create a better world.

I'm physics Student and i teach physics from 3 year the projectile motion is very interesting topic in motion this video very helpful and effective also for me.
This is great and clearly explanation of projectile motion under gravity this is very helpful for every one who seen this
Best video ever about projectile motion.thank you from an engineer & physics teacher

and also the kinetic energy is also same of both initialy
@@JEE-ff5pp okay sir
Thank you very much for the explanation in an animated form.......Hats off and sincere thanks...
Words can't express my gratitude towards you! Thank you soooo muchh!!!
Ma'shAllah, Very well explained sir.
very helpful and the first time I got this more clearly 😍❤

Cool graphics and clear explanation 🙂👌... Keep up the great work 👍🏼
Alhamdulillah nicely explained law of projectile
Happy Teachers day Sir, thanks for making our lives better and happier :)

Please, Sabin has a great time explanation, it will help other students when we share this channel

Anda orang yg hebat kawan. Saya bisa memahami kinerja mesin yg bagus setelah menonton saluran lesics Indonesia 🇮🇩
Terimakasih 🙏
( cv) . your explanation made physics easy for us 😀 😍🙏

Range at 60° and 30° are equal
It's actually fun to learn with you videos! An pretty good explanation! Thanks. 😊
Wow!! Very interesting. Thanks for explanation.
Excellent explanation ever!!
thank you for very clear and easy to understand video

30 degrees, not 60
❤❤❤wow what a perfect illustration ✨️♥️♥️🔥🔥🔥 best illustration ever❤❤❤🤞🤞🤞
sir well defined. sir plz upload more videos like this its really helpful for students

Air resistance will make the horizontal speed to decrease from the moment the stone/object leave the hand, cannon or whatever it is...
thank you so so much!! just started A level physics and this helped me get the hang, thanks again :)

THIS JUST BLEW MY MIND THANK YOU SO MUCH
Beautiful to see.
The best angle depends on the amount of wind resistance the object has. The ideal angle will be below 45, usually around 25 to 35 degrees.
agreed. the creator of this video was assuming a vacuum, with gravity being a vector orthogonal to a plane.
Pi/2 baby!
@@SuperEuclideanwind resistance is negligible to high dense rocks
But generally in most grade subjects the question specifies that we neglect the winds resistance and he explains based off that
Interesting ☺️
Buy more on this topic is needed.
Whan an beautiful explanation 👍
What a clarification!
what software you use to make such video
I remember artillery exercises where we tried to blow up a farmer’s well, got the math wrong and took out an entire herd of his cows.
Both stones do not land at the same time. The one thrown horizontally has a longer path, so air friction will slow it down a tiny bit more, increasing the time it takes to get to the water. If you said the 2 stones will hit the water at aproximately the same time you would have been correct. Air friction also makes 60 degrees the optimal angle for greatest range on large cannon projectiles.
Apparently you've never been around any weapons that fire bullets. Because this may be true in the absence of atmosphere. The longest range is somewhere between 33 and a half to 35 degrees of inclination. But that's in actual practice on our Earth.
Thank you for saying "perfectly horizontally".
The best way to learn physics,, thanks
Do go on to teach your students through these techniques because everybody satisfy with pictures. Thank you.
Great work sir
best explanation out there
Strange... amazing science
Yes this is right you are good for me 😊
Suppose you and you friend stand at the edge of a cliff, then you throw your friend off. How far will he fly?
this means that you can throw a ball horizontally with enough initial velocity that it orbits the world before returning and landing behind you at your feet, and drop a ball from your other hand and from the same height as the throw, and they will still hit the ground at the same time.
that's a different thing
yes correct. it is obvious if a ball has horizontal velocity ,it will follow projectile path before hitting ground. it will spend more time in air as compared to ball with zero horizontal velocity. spending more time in air means delay in hitting ground.
Not quite.
Very interesting video 🙂 👍👍👍👍👍🚀🚀🌏
Loved it ❤️
I hope u will decide to publish more videos like this... it was great... ;) congratulations. ciao Fromm Italian teacher
Amazing, Sir!💕
This video said "The maximum range happen for a 45° angle". That's fals EXEPT if they add "Without taking count of the air friction. Since the represent a cannon that's not true in that exemple
Add some air resistance and wind drift of the projectile and cone shape with balistic coefficient. Then calculate the trajectory and flight path.
Genius explanation. 👍🏻👍🏻
Both the objects will not reach the ground at the same time ❗
Since, both the objects are under the influence of same gravitational acceleration. Also the horizontal motion of the thrown object, doesn't have any affect on its vertical motion.

Well explained 🎉
I really injoy this video
That was good.
The maximum range for a projectile is achieved when the starting angle and the end angle is at 90 degrees to each other. That angle is not always 45 degrees of course. It depends on the height difference of the start and end.
Best explanation
India is good
Plzz make more videosss i loved the way you explain.....

This video very well.❤
Awesome visualization🌼
Very nice 👍👍👍👍👍
In projectile we say that only vertical component of velocity change not horizontal component if there is no drug force,sir am i right
Nice video, informative.
Awesome... Very informative
why don't you do this same channel but in portuguese I'm bazileiro so I want the same videos from this channel in portuguese
Satisfied 💛💛💛☺️☺️😊
.love you brothrer muwahhh thxxx
Very helpful
Thank you sir ...pls keep uploading videos..
Nice sir 🥰
Good video!
Great
yes but it doesnt factor in wind resistance , wind drift or any lifting spinning factors
No hand thrown object describes a parabola. A parabola describes a uniform curve. Any hand thrown object describes a gentle curve at first. Later in its flight the arc becomes more pronounced so the arc is not uniform as in a parabola.
Small doubt if the ball is thrown in angle of complementary the they final destination is same right
Nice analysis
Thank you so much ,God bless!
Nice videos! You really deserve more views!
0:43 It is not truly parabolic due to the air resistance.
Amazing 👌
Gacor kang
Thank you for the video.
Nice understanding
