Momentum and Energy Test

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created or destroyed, only transferred or converted from one form to another.

Front

How can you increase power when running upstairs?

Back

By increasing your speed.

Front

What is the formula for calculating work?

Back

Work = Force x Displacement.

Front

What is work defined as?

Back

The product of force and distance.

Front

If the velocity of a moving object is doubled, how does its kinetic energy change?

Back

The kinetic energy becomes four times as big.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 mv², where m is mass and v is velocity.

Front

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

Back

The unit of work is the Joule (J).

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy.

Front

What is potential energy?

Back

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