Momentum and Impulse Conceptual Questions

Front

What does impulse depend on?

Back

Impulse depends on force and time.

Front

What do both students experience during a collision?

Back

Both students experience the same force of impact, time of impact, and change in momentum.

Front

Calculate the impulse on a football kicked with a force of 20 N for 0.3 s.

Back

Impulse = Force × Time = 20 N × 0.3 s = 6 N.s.

Front

What happens to an egg dropped on water compared to one dropped on the ground in terms of force and time?

Back

The egg dropped on water experiences less force, but more time.

Front

What does the momentum of an object depend on?

Back

The momentum of an object depends on its mass and velocity.

Front

Define impulse in physics.

Back

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

Front

What is the formula for calculating impulse?

Back

Impulse = Force × Time.

Front

How does increasing the time of impact affect the force experienced?

Back

Increasing the time of impact decreases the force experienced.

Front

What is the relationship between momentum and velocity?

Back

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

Front

If two objects have the same momentum, what can be said about their mass and velocity?

Back

If two objects have the same momentum, their mass and velocity can vary, but their product (mass × velocity) will be equal.
