Collisions
Is momentum conserved in a collision, along with energy, or are they opposing forces? Pupils vary the mass and velocity of two bumper cars along with the type of bumper in order to answer this question. Worksheet and in-simulator...

Car Collision
When a car crashes into a wall, does it just stop or does it bounce or roll backwards? A simulation relates velocity, kinetic energy, momentum, and restitution to answer this question. Scholars apply their knowledge through eight levels...

Bumper Cars
Is the transfer of energy different in bumper cars with stable versus bouncy bumpers? One of the variables explored in the simulation is bumper type; other variables are the mass and velocity of each car. This allows pupils to see the...
