| Energy conservation | management of the use of energy resources |
| Energy resources | Natural resources used as a source of energy |
| Balanced force | Equal and opposite forces on an object that result in no change in position, direction or movement. ( not moving) |
| Unbalanced force | unequal forces on an object that may result in a change in position, direction, or movement |
| Model | a picture idea or object that represents an object, a system, or a process and is used to help with understanding models have advantages and limitations |
| Conductivity | ability to conduct electrical current |
