Collisions

Front

What type of collision conserves kinetic energy?

Back

Elastic collision.

Front

What is the energy released to the surroundings during a collision called?

Back

Heat (dissipates).

Front

How is momentum after a perfectly inelastic collision expressed?

Back

Front

How is momentum before a collision expressed?

Back

Front

What type of collision occurs when two objects bounce and move separately while kinetic energy is not conserved?

Back

Inelastic collision.

Front

Define an elastic collision.

Back

A collision in which both momentum and kinetic energy are conserved.

Front

Define a perfectly inelastic collision.

Back

A collision in which the two objects stick together after colliding, conserving momentum but not kinetic energy.

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

What happens to kinetic energy in an inelastic collision?

Back

Kinetic energy is not conserved; some energy is transformed into other forms.

Front

What is the formula for kinetic energy?
