What is momentum?

Back

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

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the unit of momentum?

Back

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

Front

If a car has a mass of 1200 kg and is moving at 5.0 m/s, what is its momentum?

Back

6000 kg m/s.

Front

What happens to the momentum of an object at rest?

Back

An object at rest has a momentum of 0 kg m/s.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

At which position is the roller coaster car's mechanical energy 100% potential energy?

Back

Position A.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv².

Front

What is an elastic collision?

Back

An elastic collision is a collision in which both momentum and kinetic energy are conserved.
