Conservation of Momentum

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v)

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

If a 0.145 kg baseball is thrown at 44.7 m/s, what is its momentum?

Back

6.4815 kg*m/s

Front

What happens to the momentum of an object if its velocity doubles?

Back

The momentum doubles.

Front

What is Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration)

Front

When two objects collide, what principle explains their momentum after the collision?

Back

The conservation of momentum.

Front

If an object with a mass of 12 kg is moving at 10 m/s, what is its momentum?

Back

120 kg*m/s

Front

What does the conservation of momentum state?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass; as mass increases, momentum increases if velocity is constant.
