Momentum and Impulse Concepts

Front

What is the definition of momentum?

Back

Momentum is defined as 'mass in motion'. It is the product of an object's mass and its velocity.

Front

How is impulse calculated?

Back

Impulse is calculated as the product of force and the time duration over which the force acts: Impulse = Force × Time.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object: Impulse = ΔMomentum.

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event (Law of Conservation of Momentum).
