Front

What are the two factors that determine the amount of kinetic energy an object has?

Back

mass & speed

Front

What is potential energy?

Back

Energy that is stored in the position, or structure, of an object.

Front

What does the law of conservation of energy state?

Back

Energy cannot be created, or destroyed.

Front

What is kinetic energy?

Back

The energy of a moving object.

Front

What do you call the ability to do work?

Back

Energy.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 * mass * speed^2.

Front

What is an example of potential energy?

Back

A drawn bow or a book on a shelf.

Front

What is an example of kinetic energy?

Back

A rolling ball or a running person.

Front

How can energy be transformed?

Back

Energy can change from one form to another, like potential energy to kinetic energy.

Front

What is mechanical energy?

Back

The sum of potential and kinetic energy in an object.
