Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula: Momentum (p) = mass (m) × velocity (v).

Front

What is the unit of momentum?

Back

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

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming the velocity remains constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming the mass remains constant.

Front

What is the law of conservation of momentum?

Back

The law of conservation of momentum states that the total momentum of a closed system remains constant unless acted upon by external forces.

Front

If two objects collide, what happens to their momentum?

Back

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

Front

What is an example of a large momentum object?

Back

A fire engine moving at high speed has a large momentum due to its mass and velocity.

Front

What is an example of a small momentum object?

Back

A frisbee moving at the same speed as a fire engine has much less momentum due to its smaller mass.

Front

What is the formula to calculate momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

Is momentum a scalar or vector quantity?

Back

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