Force

A push or pull on an object that can cause it to move.

Energy

The ability to do work. It's the energy transferred when an object is moved by a force.

Work

The amount of energy needed to move an object is directly related to the force applied and the distance moved.

Heavier Objects Require More Energy

A larger force is needed to move a heavier object. This means more energy is required.
