Momentum and the Law of Conservation of 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 factors affect the momentum of an object?

Back

The momentum of an object depends on its 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 SI unit of momentum?

Back

The SI unit for momentum is kilogram meter per second (kg m/s).

Front

What happens to the momentum of an object if its velocity changes?

Back

If an object's velocity changes, its momentum will also change.

Front

What is the Law of Conservation of Momentum?

Back

The Law of Conservation of Momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

If two objects collide, what can be said about their total momentum?

Back

The total momentum of the two objects before the collision is equal to the total momentum after the collision, assuming no external forces act on them.

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 is an example of momentum in everyday life?

Back

A moving car has momentum due to its mass and speed; a heavier car moving at the same speed has more momentum than a lighter car.
