Front

The momentum of an object depends upon the object's ___________&_____________.

Back

Mass and velocity

Front

What is the formula for calculating momentum?

Back

Momentum = Mass × Velocity

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and momentum?

Back

Impulse equals the change in momentum.

Front

What is the unit of momentum?

Back

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before and after a collision remains constant.
