United Scientific Ballistics Car W/ Remote Trigger

United Scientific Supply This Ballistics Car demonstrates the independence of vertical and horizontal motions It consists of a four-wheeled cart carrying a vertical tube with a spring-loaded piston inside The tube is loaded with a ball and the cart is set in motion During the 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 backin the tube and does not get left behind by the cartCart includes a conical rubber catcher to compensate for slight trajectory variations Supplied with two 34 steel balls Requires one 9V battery (not included) Includes activity guide - USS
