Momentum and Impulse Conceptual Questions

Front

What is impulse in relation to momentum?

Back

Impulse is equal to the change in momentum.

Front

What two factors does the momentum of an object depend on?

Back

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

Front

What happens to the force experienced by an egg dropped into water compared to one dropped onto a hard surface?

Back

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

Front

What does impulse depend on?

Back

Impulse depends on force and time.

Front

If a cart has a momentum of 16 kg m/s and a mass of 2 kg, what is its velocity?

Back

The velocity of the cart is 8 m/s.

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

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

Front

How does increasing the time of impact affect the force experienced by an object?

Back

Increasing the time of impact decreases the force experienced by the object.

Front

What is the relationship between impulse and force?

Back

Impulse is the product of force and the time duration over which the force acts.

Front

What is the unit of momentum?

Back

The unit of momentum is kg m/s.
