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

What are the two main factors that determine momentum?

Back

Mass and velocity.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What is the law of conservation of momentum?

Back

In an isolated system, the total momentum before an event is equal to the total momentum after the event.

Front

How does mass affect momentum?

Back

An increase in mass will result in an increase in momentum if velocity remains constant.

Front

How does velocity affect momentum?

Back

An increase in velocity will result in an increase in momentum if mass remains constant.

Front

What happens to the momentum of two skaters who push off each other?

Back

The total momentum of the system remains constant, but the individual momenta change.

Front

If a runner has a momentum of 720 kg m/s and is traveling at a velocity of 5 m/s, what is their mass?

Back

144 kg.

Front

What is the formula for calculating momentum?

Back

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

Front

What is an example of momentum in everyday life?

Back

A moving car has momentum due to its mass and speed.
