Demonstrate the independence of the horizontal and vertical components of projectile motion.

• Ping pong ball is clearly visible during flight
• Projectile is safe for classroom use
• Apparatus can also be used for general projectile motion investigations

This apparatus illustrates the effect of gravity on the projectile motion. An elastic-powered gun is supported from a battery-operated small electromagnet. It fires ping-pong ball 'bullets' at a model monkey. When the projectile is fired, the electromagnetic circuit breaks. The trajectory is easily visible. Both monkey and bullet fall at the same rate and the bullet always hits the monkey regardless of how far away the monkey is.

This proves that the horizontal and vertical motions are independent of each other. This unit includes a table clamp mounting plate and it may also be used as a trajectory apparatus. Requires support stand and low voltage battery, which is not provided with the apparatus.
