This is a demonstration of
This is a demonstration of the independence of the horizontal and vertical components of the velocity of a projectile. For more details see http://sciencedemonstrations.fas.harv...
In this video we see the spring-powered gun shooting the same steel ball bearing with two different initial velocities in an attempt to show that the initial speed of the ball does not matter. The shots at 0:51, 1:00, and 1:09 are close to the maximum speed (roughly 13 m/s), while the shots at 1:18, 1:27, and 1:34 are close to the minimum (roughly 9 m/s). All other parameters remain the same for all trials; the horizontal distance is about 6.9 meters, and the launch angle is about 23 degrees above the horizontal.
