this wooden carts have accurately aligned axles, they yield superior data for all quantitative kinematics experiments. With a low profile
and three widely spaced wheels for stability, each features a Velcro attachment for studying inelastic collisions
and an easily set firing mechanism with two firing positions. The carts can be towed with rubber bands to simulate the application of constant forces.
