W HAT IS ENERGY ? The ability to do work The power to change things Types of Energy (US Dept of Energy) Stored (Potential) energy: The capacity for doing work Working (Kinetic) energy: Conversion of the capability to motion Pencil example: Put a pencil at the edge of the desk and push it off to the floor. The moving pencil uses kinetic energy. Now, pick up the pencil and put it back on the desk. You used your own energy to lift and move the pencil. Moving it higher than the floor adds energy to it. As it rests on the desk, the pencil has potential energy. The higher it is, the further it could fall. That means the pencil has more potential energy.
