What is projectile launcher?
Launcher The Projectile Launcher is used to investigate important concepts in two- dimensional kinematics. A steel ball placed in the launch barrel can be projected for different launch velocities and launch angles. Upon setting the desired angle and range, the hand pump is then used to pressurize the system.
Why do ping pong balls bounce so high?
when you throw a ping pong ball at (a preferable hard) surface, because it is made of thin plastic and is hollow inside, it easily compresses into itself for a brief moment before returning to it’s original shape causing it to push off of the surface it hit causing it to bounce.
Why does a ping pong ball float in air?
This is due to gravity. Gravity is a force that pulls objects toward each other. The ball “floats” in the air at an even point when the force of gravity (which is forcing the ping pong ball down) is equal to the force of the air stream from the hair dryer (which is pushing the ping pong ball up).
