Momentum

Front

What is the definition of momentum?

Back

Momentum is defined as 'mass in motion.' It is the product of an object's mass and its velocity.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula: p = mass (m) x velocity (v).

Front

What is the unit of momentum?

Back

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

Front

If a 1000-kg car is moving at 20 m/s, what is its momentum?

Back

The momentum of the car is 20000 kg * m/s south.

Front

What happens to momentum if the mass of an object is doubled?

Back

If the mass of an object is doubled, its momentum also doubles, assuming velocity remains constant.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

Which has more momentum: a stationary car or a moving bike?

Back

A moving bike has more momentum than a stationary car.

Front

What is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass; as mass increases, momentum increases if velocity is constant.

Front

What is the relationship between velocity and momentum?

Back

Momentum is directly proportional to velocity; as velocity increases, momentum increases if mass is constant.

Front

If a toy car has a mass of 2 kg and is moving at 0.5 m/s, what is its momentum?

Back

The momentum of the toy car is 1 kg * m/s.
