Momentum

Front

What is momentum?

Back

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

Front

If an object has a velocity of 0 m/s, what can be said about its momentum?

Back

The object has no momentum.

Front

How does the velocity of an object affect its momentum?

Back

The momentum of an object increases with an increase in its velocity, as momentum is directly proportional to velocity.

Front

What are the two factors that determine the momentum of an object?

Back

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

Front

If two identical cars are traveling at different speeds, how do their momenta compare?

Back

The car traveling at the higher speed will have greater momentum.

Front

Calculate the momentum of a 1000-kg car moving at 20 m/s.

Back

The momentum is 20000 kg*m/s north.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg*m/s).

Front

If Object A has a mass of 5 kg and is moving at 10 m/s, what is its momentum?

Back

The momentum of Object A is 50 kg*m/s.

Front

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

Back

The momentum of the object will also double.

Front

In a collision, how is momentum conserved?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision.
