This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

• Operating Instructions Included
• Two Steel Balls Included
• For Demonstrating the Independence of Vertical and Horizontal Motions
• Conical Rubber Catcher Included
• Spring-Loaded Piston

It consists of a four-wheeled cart carrying a vertical tube with a spring-loaded piston inside. The tube is loaded with a ball. When the cart is set in motion, the piston is released remotely by a wireless signal, projecting the ball upwards out of the tube. Both the ball and the cart share the same horizontal velocity, which is unaffected by gravity, so that when the ball falls back down, it lands back in the tube and does not get "left behind" by the cart.

The cart includes a conical rubber catcher to compensate for slight trajectory variations.
