High-impact plastic carts for any mechanics experiment involving linear motion. The three ball-bearing wheels provide smooth operation, and the top is designed to accommodate our liquid accelerometer or up to five ordinary bricks as test masses.
One cart includes a spring-loaded plunger for initiating repeatable collisions at two different tensions. Long rubber bands are included for applying constant forces to the carts. Carts can be used with any motion sensor or tape timer. 12" long.Liquid Accelerometer not included!
