Grades 9 and up. This lightweight, nearly frictionless Hall’s Car is ideal for studying the relationship between work and energy. It demonstrates the vector forces in acceleration or static force studies and can be used to determine the coefficient of friction of a rolling surface. Features oil-free sleeve bearings that never need adjustment and a wide body with low profile for bulk loads. Both the body and wheels are made from high-impact, colorful ABS plastic. The recession in the car allows for additional weight. Wheels snap back into place if dropped. Contains punched hole for attaching hook or string, useful with an incline plane. Includes instructions.
