AP Physics Lab 4: Horizontal Motion

Investigate the path of a horizontally-launched projectile and then predict where the ball will land. In this experiment, a ball rolled horizontally off a table allows students to measure the launch velocity and reinforces the idea that horizontal velocity remains constant, while the vertical velocity increases. The kit includes a curved ramp, steel and wooden balls, plumb line, C-clamp, golf ball, stopwatch, calipers, and a catch cup. Required but not included are a meterstick and a photogate system.
