Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p = mv.

Front

What is the formula for calculating momentum?

Back

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

Front

Is momentum a scalar or vector quantity?

Back

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

Front

If the speed of an object is doubled, what happens to its momentum?

Back

The momentum doubles.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

Which of the following has the least amount of momentum: an ant walking, an ant at rest, or an elephant walking?

Back

An ant at rest has the least amount of momentum.

Front

What happens to momentum when mass is increased while keeping velocity constant?

Back

Momentum increases.

Front

What happens to momentum when velocity is decreased while keeping mass constant?

Back

Momentum decreases.

Front

What is the unit of momentum in the International System of Units (SI)?

Back

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

Front

How does the direction of momentum relate to the direction of velocity?

Back

The direction of momentum is the same as the direction of velocity.
