Serc: Conservation of Momentum Using Rollerblades and a Medicine Ball
In this guided inquiry demonstration, a person on rollerblades and a medicine ball are used to teach the concept of conservation of momentum. Various sorts of collisions are used to show how momentum is conserved within a system.

Serc: Exploring Newton's Second Law
Students conduct an experiment that will reinforce their understanding of Newton's Second Law. Using simple objects, students control force, mass, and acceleration, and how each is related to each other.

The Physics Classroom: Momentum and Collisions: Cart and Brick Interactive
Students analyze a collision between a moving cart and a dropped brick that lands on top of it. They use position-time data to determine the pre- and post-collision speeds of the cart and the brick. The individual momentum values of the...

The Physics Classroom: Momentum and Collisions: Exploding Carts Interactive
Students explore different situations where two side-by-side carts on a low-friction track push away from each other and travel in opposite directions. The goal is to investigate the effects on the relative mass.
