Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What are the units of momentum?

Back

The units of momentum are kilogram meters per second (kg * m/s).

Front

If a car has a mass of 1000 kg and is moving at 20 m/s, what is its momentum?

Back

20000 kg * m/s south.

Front

True or False: A stationary object has momentum.

Back

False.

Front

Which has greater momentum: a 0.15 kg object moving at 2 m/s or a 0.4 kg object moving at 1 m/s?

Back

A 0.4 kg object moving at 2 m/s has greater momentum.

Front

What happens to momentum if the mass of an object increases while its velocity remains constant?

Back

The momentum increases.

Front

What happens to momentum if the velocity of an object decreases while its mass remains constant?

Back

The momentum decreases.

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

If two objects collide and stick together, how is their combined momentum calculated?

Back

The combined momentum is the sum of their individual momenta before the collision.
