Energy and Motion

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, gasoline in a gas tank has potential energy.

What happens to an object at rest if no outside forces are applied?

Back

An object at rest will stay at rest.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction. For example, when you hit a wall with a stick, the wall pushes against the stick.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. For example, a car driving down the highway has kinetic energy.

Front

What is the ultimate source of energy for Earth?

Back

The ultimate source of energy is the sun.

Front

What is the difference between Kinetic Energy and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on position.

Front

Can energy be transformed from one form to another?

Back

Yes, energy can be transformed from one form to another, such as potential energy converting to kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

An example of Potential Energy is a book on a shelf. It has potential energy due to its height.

Front

What is an example of Kinetic Energy in everyday life?

Back

An example of Kinetic Energy is a basketball being dribbled.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion, slowing down or stopping moving objects.
