Momentum and Impulse

Front

What does the Law of Conservation of Momentum state?

Back

If interacting objects in a system are not acted on by outside forces, the total amount of momentum in the system can not change.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the momentum of a car with a mass of 2500 kg traveling at 30 m/s?

Back

75,000 kg x m/s.

Front

If a 5.5 kg ball has a momentum of 25 kg x m/s, how fast is it traveling?

Back

4.5 m/s.

Front

What does 'p' represent in the equation p = mv?

Back

p represents momentum.

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

How is impulse calculated?

Back

Impulse is calculated using the formula Impulse = Force x Time.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration.

Front

What is the unit of momentum?

Back

The unit of momentum is kg x m/s.

Front

What happens to momentum in a closed system during a collision?

Back

The total momentum before the collision is equal to the total momentum after the collision.
