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.
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.
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.
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.
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.
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!
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.
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.
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!
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.
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 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.
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.
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.
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.
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 something schools can't teach properly. Sabin has always been helpful.
45 deg is just common sense but there's none of that today... UA-cam videos to the rescue
Absolutely right 👍
Absolutely Right 💯💯✅✔✔

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.
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...
Please, Sabin has a great time explanation, it will help other students when we share this channel
Words can't express my gratitude towards you! Thank you soooo muchh!!!

and also the kinetic energy is also same of both initialy
@@JEE-ff5pp okay sir
Cool graphics and clear explanation 🙂👌... Keep up the great work 👍🏼
Wow!! Very interesting. Thanks for explanation.
Anda orang yg hebat kawan. Saya bisa memahami kinerja mesin yg bagus setelah menonton saluran lesics Indonesia 🇮🇩

Happy Teachers day Sir, thanks for making our lives better and happier :)
Ma'shAllah, Very well explained sir.
very helpful and the first time I got this more clearly 😍❤
sir well defined. sir plz upload more videos like this its really helpful for students
Alhamdulillah nicely explained law of projectile
THIS JUST BLEW MY MIND THANK YOU SO MUCH

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 🤷♂️
( cv) . your explanation made physics easy for us 😀 😍🙏
Interesting ☺️
Buy more on this topic is needed.
It's actually fun to learn with you videos! An pretty good explanation! Thanks. 😊
thank you for very clear and easy to understand video

Won't the air friction also affect the stone speed in the first case assuming stones are of different shapes?
I hope u will decide to publish more videos like this... it was great... ;) congratulations. ciao Fromm Italian teacher
Excellent explanation ever!!
Genius explanation. 👍🏻👍🏻
Wow great explanation ❤

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.
30 degrees, not 60
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.
Whan an beautiful explanation 👍
thank you so so much!! just started A level physics and this helped me get the hang, thanks again :)
i remember at 2020 i taught my student about 45 degree angle to obtain the longest distance.

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!
Plzz make more videosss i loved the way you explain.....
best explanation out there
The best way to learn physics,, thanks
Well explained 🎉
Good video!
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
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.
Beautiful to see.
Thank you for saying "perfectly horizontally".
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."
Loved it ❤️
Yes this is right you are good for me 😊
Thank you sir ...pls keep uploading videos..
This video very well.❤
Amazing, Sir!💕
Satisfied 💛💛💛☺️☺️😊
Awesome visualization🌼
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.
Air resistance will make the horizontal speed to decrease from the moment the stone/object leave the hand, cannon or whatever it is...
Do go on to teach your students through these techniques because everybody satisfy with pictures. Thank you.
What a clarification!
I really injoy this video
Strange... amazing science
what software you use to make such video
Great work sir
.love you brothrer muwahhh thxxx
Very nice 👍👍👍👍👍
Thank you for the video.
Very interesting! Thank you.

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 videos! You really deserve more views!
That was good.
Best explanation
India is good
Thank you so much ,God bless!
Awesome... Very informative
Nice video, informative.
Can you make the same video on projectile on an inclined plane
In projectile we say that only vertical component of velocity change not horizontal component if there is no drug force,sir am i right

Add some air resistance and wind drift of the projectile and cone shape with balistic coefficient. Then calculate the trajectory and flight path.
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.
Excellent..!
Small doubt if the ball is thrown in angle of complementary the they final destination is same right
Make another part with additional component like wind velocity.
Keep trying keep growing 👍
Nice analysis
Amazing man❤️🥺
Amazing 👌

If time is distance ÷speed
And both have same speed throughout and same time to reach ground does that mean they hv travelled same distance?
Vertically, yes. Horizontally, no

Why you stop making video, Please continue it sir, Your video are great
0:43 It is not truly parabolic due to the air resistance.
