elastic&inlastic collisions

Front

What is an inelastic collision?

Back

An inelastic collision is when two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy).

What is an elastic collision?

Back

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

How is kinetic energy affected in an inelastic collision?

Back

Kinetic energy is partially lost to other forms of energy.

Front

Kinetic energy is conserved __________ collisions.

Back

only in elastic.

Front

Momentum is conserved __________ collisions.

Back

in all.

What happens to momentum in an elastic collision?

Back

Momentum is conserved and the total momentum before and after the collision remains the same.

What happens to momentum in an inelastic collision?

Back

Momentum is conserved, but kinetic energy is not.

Back

Yes, in an inelastic collision, two objects can stick together.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, momentum is conserved but kinetic energy is not.
