6 test review momentum, impulse, collisions

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

What is the formula for impulse?

Back

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum.

Front

What is the unit of impulse?

Back

The unit of impulse is Newton-seconds (N·s).

Front

What is momentum?

Back

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram-meters per second (kg·m/s).

Front

How do you calculate the change in momentum?

Back

Front

If a 40 kg mass is moving at 5 m/s, what is its momentum?

Back

Front

What happens to momentum in a collision?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision (conservation of momentum).

Front

What is a perfectly elastic collision?

Back

A perfectly elastic collision is one in which both momentum and kinetic energy are conserved.
