Energy Test Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

Front

Where is the maximum kinetic energy on a roller coaster?

Back

At the bottom of the first hill.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is highest when an object is at its highest point.

Front

Where is the maximum potential energy on a roller coaster?

Back

At the top of a big hill.

Front

What does the Law of Conservation of Energy state?

Back

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

Front

What is an example of energy transformation from chemical to mechanical?

Back

A person running.

Front

What is an example of energy transformation from electrical to mechanical to sound?

Back

Using an electric pencil sharpener.

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What type of energy does a candle burning produce?

Back

Chemical energy is transformed into thermal energy and light.
