Vertical Acceleration Demonstrator

Student can visualize acceleration due to gravity!

No beginning physics student should miss this. It dramatically demonstrates a concept that is crucial for understanding projectile motion: the independence of horizontal and vertical components of projectile motion. Two balls are mounted on the apparatus. When you release the spring, one is dropped directly down while the other is projected horizontally. Listen, and you'll hear that both hit the floor at the same time! Easy to set up and level. An S Clamp and Ring Stand are required items.
