| control | something that stays the same during your experiment |
| variable | something that you choose to change during your experiment |
| motion | a change in position of an object |
| position | where an object is located |
| force | a push or pull that can change the motion or position of an object |
| friction | a force that acts in an opposite direction to movement |
| gravity | a force that pulls objects toward each other |
| magnetism | a force that pushes or pulls a magnetic material |
| push | the act of applying force in order to move something away |
| pull | the act of applying force to move something toward or with you |
| reliable | when an experiment gives you the same results each time you do it |
| fair test | a test with only one variable |
| equal forces | forces that act together on an object without changing its motion |
| unequal forces | forces that cause an object to start or stop moving |
| energy transfer | the movement of energy from one object to another |
