The Elastic Collisions Activity coordinates with the Collision Carts simulaton found in our Physics Interactives section. The simulation engages students in an interactive exploration of the law of momentum conservation for colliding objects. The Interactive is accompanied by a classroom-ready activity sheet that can be distributed to students.

## Frequently Asked Questions

### What is the elastic collision formula??

The elastic collision formula comprises two parts, namely elastic collision formula for kinetic energy and elastic collision for momentum. A fundamental way to make sure whether a collision is elastic or inelastic is by equating their total kinetic energy.

### Why would we ever approximate a collision as perfectly elastic??

Collisions of rigid billiard balls or the balls in a Newton's cradle are two such examples. Why would we ever approximate a collision as perfectly elastic? Given that no mechanics problem we are likely to encounter involves a perfectly elastic collision, it may seem that the concept is of little practical use.

### Are momentum and kinetic energy conserved in elastic collisions??

Both momentum and kinetic energy are conserved quantities in elastic collisions. Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed.

### What is an inelastic collision??

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not.
