Dynamics Trolleys - Plastic

A pair of carts, made from a single piece of moulded unbreakable ABS. These carts are rigid and strong enough to withstand routine rough usage or falls from workbench etc. 3 low friction wheels providing straight motion over long distances. A lockable spring-loaded exploder plunger has 2 levels of spring compression and is activated by a trigger on top of the trolley. A cushioned surface mounted on top of each cart enables placing of additional masses for increasing the effective weight of the cart. The carts can be stacked on top of each other to double or triple the overall mass. Velcro at the back end of each cart enables the study of inelastic collisions.
