Momentum Pre-assessment

Front

What is impulse in relation to momentum?

Back

Impulse is equal to the change in momentum.

Front

What two factors does momentum depend on?

Back

Momentum depends on mass and velocity.

Front

What is the equation to calculate momentum?

Back

p = mv

Front

What happens to the total momentum in a collision?

Back

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

Front

How do you calculate impulse?

Back

Impulse = Force × Time.

Front

If a force of 20 N acts for 0.3 s, what is the impulse?

Back

Impulse = 20 N × 0.3 s = 6 N*s.

Front

What is the unit of momentum?

Back

The unit of momentum is kg·m/s.

Front

What is the principle of conservation of momentum?

Back

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

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

How does velocity affect momentum?

Back

Greater velocity results in greater momentum if mass is constant.
