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.
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.
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 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.
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.
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.
To everyone saying he forgot air resistance, the video explains projectile motion when air resistance is negligible. I assume most of the people saying that are in 11th grade or above because I’m in 8th grade and this is the exact projectile motion we do in class, and my teacher said this is the projectile motion when air resistance is negligible. So if you’re looking for a video with air resistance being a factor, then you need a more complex explanation than this.
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.
i remember at 2020 i taught my student about 45 degree angle to obtain the longest distance. and then, at 2021, i was cooking and went to backyard while i forgot to turn off the stove. When i'm back, the fire has already reached the roof. I was screaming at that time, but i'm also gathering many water i can get, and got the fire on the wall off... the only fire i can't get it off is the fire on the roof... i went outside and try to throw water, but it can't reach the fire... no matter how much i tried, the water can't reach the fire.... untillll i remember about something i taught my student... it was projectile motion with 45 degree angle.. when i applying that angle, finally the water could reach the fire, and put it off!
R(horizontal range) = V(initial velocity) × sin2theta ÷ g(acceleration) And sin2theta is maximum for theta=45. So, you if you throw a ball horizontally at 45°, distance of the ball hits the ground is maximum.
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.
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.
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."
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
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.
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.
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.
Ballistics too - fire a gun parallel to the ground and drop a marble from the bore hight simultaneously, and both will hit the ground at the same time; bullet and marble.
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.
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 great and clearly explanation of projectile motion under gravity this is very helpful for every one who seen this
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.
and also the kinetic energy is also same of both initialy

Best video ever about projectile motion.thank you from an engineer & physics teacher
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!!!
Very Useful VDO. I am a physics teacher and showed this VDO to both of my Grade 11 classes. Thank you very much for your dedicated work.
Alhamdulillah nicely explained law of projectile

It's the introduction drag is something you learn later on
That is something for later studies when we have a better understanding of physics and its formulas 🤷♂️
THIS JUST BLEW MY MIND THANK YOU SO MUCH

sir well defined. sir plz upload more videos like this its really helpful for students
Interesting ☺️
Buy more on this topic is needed.

30 degrees, not 60
i remember at 2020 i taught my student about 45 degree angle to obtain the longest distance.

the only fire i can't get it off is the fire on the roof... i went outside and try to throw water, but it can't reach the fire...
no matter how much i tried, the water can't reach the fire.... untillll
i remember about something i taught my student...
it was projectile motion with 45 degree angle..
when i applying that angle, finally the water could reach the fire, and put it off!
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
Air resistance is ignored
R(horizontal range) = V(initial velocity) × sin2theta ÷ g(acceleration)
And sin2theta is maximum for theta=45. So, you if you throw a ball horizontally at 45°, distance of the ball hits the ground is maximum.
Genius explanation. 👍🏻👍🏻
The best way to learn physics,, thanks
Whan an beautiful explanation 👍
Beautiful to see.
Well explained 🎉
Wow great explanation ❤
Yes this is right you are good for me 😊
I hope u will decide to publish more videos like this... it was great... ;) congratulations. ciao Fromm Italian teacher
Good video!
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

Not quite.

Very interesting! Thank you.
Air resistance will make the horizontal speed to decrease from the moment the stone/object leave the hand, cannon or whatever it is...
Satisfied 💛💛💛☺️☺️😊
Awesome visualization🌼
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.
Nice video, informative.
Add some air resistance and wind drift of the projectile and cone shape with balistic coefficient. Then calculate the trajectory and flight path.
Very nice 👍👍👍👍👍
Thank you sir ...pls keep uploading videos..
That was good.
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

What a clarification!
Great work sir
Do go on to teach your students through these techniques because everybody satisfy with pictures. Thank you.

Make another part with additional component like wind velocity.
Both the objects will not reach the ground at the same time ❗

The vertical velocity both the objects are same at any given time during their fall and both the objects falls from the same height.

its very simple to understand
0:43 It is not truly parabolic due to the air resistance.
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.
Amazing man❤️🥺
Ballistics too - fire a gun parallel to the ground and drop a marble from the bore hight simultaneously, and both will hit the ground at the same time; bullet and marble.
Can you make the same video on projectile on an inclined plane
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.
