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.
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.
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.
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.
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.
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.
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."
You could do a "Part 2", showing how orbits work. Fire a cannon shell at some angle, and it will fall back to the Earth. Keep the same angle, but add more gunpowder and it will fall much further away. Keep increasing the powder until the cannon ball falls beyond the horizon. At this point, it is so high that there's essentially no air to slow it down, but it keeps "falling" towards the Earth. Since the Earth is round, the ball simply flies around the Earth, perpetually falling and never hitting the ground.
@@parahattajov9359 No. The moon is not falling towards earth. It is gravitationally locked to the earth and the sun. The distance changes often, sometimes closer and sometimes further away. The Sun's gravitational effect on the Moon is more than twice that of Earth's on the Moon. A "Shell" fired into orbit, without continuous propulsion would fall back to earth because of GRAVITY.
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 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
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.
