1 Joule | Work done when a force of 1 N acts for a distance of 1 m in the direction of the force. |
Energy | Ability to do work. |
Kinetic Energy | Energy a body has due to its motion. |
Potential Energy | Energy a body has due to its position in a force field. |
Principle of Conservation of Energy | Energy cannot be created or destroyed but can only be converted from one form to another. |
Renewable Source of Energy | Energy that does not get used up. |
Non-renewable Source of Energy | Energy that will eventually get used up. |
Power | Rate at which work is done. or Rate at which energy is converted from one form to another. |
