A push or pull on an object.

Front

What is Kinetic Energy?

Back

The energy an object has due to its motion.

Front

What is Potential Energy?

Back

The stored energy of an object due to its position or state.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.
