Teach Engineering: Skateboard Disaster
Learners examine collisions between two skateboards with different masses to learn about conservation of momentum in collisions.
Physics Aviary
Physics Aviary: Practice Problems: Momentum Conservation Level 4
Students must predict the speed in a problem involving momentum conservation. The two objects have a head-on collision and stick together during the collision.
Physics Aviary
Physics Aviary: Practice Problems: Momentum Conservation Level 2
Students must determine the unknown mass in a problem involving momentum conservation. One object begins at rest and the two objects stick together during the collision.
Physics Aviary
Physics Aviary: Practice Problems: Momentum Conservation Level 3
Students must predict the speed in a problem involving momentum conservation. One object overtakes the other and the two objects stick together during the collision.
