Collisions (Conservation of Momentum)

Front

What happens during a completely inelastic collision?

Back

The objects must stick together after the collision.

Front

What defines a collision?

Back

A collision occurs when two or more objects hit each other with a force.

Front

In which type of collision is kinetic energy conserved?

Back

Kinetic energy is conserved only in elastic collisions.

Front

How is kinetic energy treated during an elastic collision?

Back

Kinetic energy is always conserved during an elastic collision.

Front

What are the two types of collisions?

Back

Collisions can be elastic or inelastic.

Front

What is the definition of an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is one in which momentum is conserved, but kinetic energy is not.

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

Can kinetic energy be converted into other forms of energy during a collision?

Back

Yes, in inelastic collisions, kinetic energy can be converted into other forms of energy, such as heat or sound.

Front

What is an example of an elastic collision?

Back

A collision between two billiard balls is an example of an elastic collision.
