#798  Impact Car. What better way to study the momentum changes of varying mass than with a visual measure of it's force.  The impact car is equipped with a spring scale and slide that is displaced on impact against a wall or similar obstacle.  This slide remains in it's displaced positioned until reset.  The student rolls the car down the ramp, and measures the impact.  Next, more mass is added inside the car and the experiment is repeated.  The student can take direct readings from the scale to measure the increasing force.  Instructions provided.
