Momentum and Impulse

Front

Momentum before = Momentum after according to the Law of Conservation of _______________.

Back

Momentum

Front

What does the impulse-momentum theorem state?

Back

Force causes a change in momentum.

Front

An object with a mass of 2000 kg at rest has what momentum?

Back

0 kg m/sec

Front

A biker with a mass of 75 kg moves along the path with a constant velocity of 5 m/s. What is the biker's momentum?

Back

375 kg m/s

Front

When the speed of an object is doubled, its momentum ______________.

Back

doubles

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time (Impulse = Force × Time).

Front

State the formula for calculating momentum.

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

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

Back

Momentum is conserved in a closed system during a collision.

Front

If two objects collide and stick together, what type of collision is this?

Back

This is called a perfectly inelastic collision.
