| Force | A push or a pull exerted on an object |
| Applied force | The directional position of a push or pull on an object (where the force is applied) |
| Reference point | Used as a frame of reference |
| Distance | Length between 2 points |
| Speed | The distance an object travels in a given amount of time (D/T) |
| Constant speed | The distance covered in a period of time is the same |
| Average speed | Calculating the total distance over the total time it takes to cover the distance |
| Velocity | The speed at which an object travels in a given amount of time in a particular direction |
| Balanced force | when two equal forces are applied to an object in opposite directions |
| Unbalanced force | when unequal force is applied causing an object to move |
| Friction | a force that opposes the motion of a body across a surface or through a gas or liquid |
| Oppose | In the opposite direction (such as with frictional force) |
| Resistance | Opposition to position or motion |
| Directly proportional | With 2 variables |
| Indirectly proportional | With 2 variables |
| Mass | the amount of matter in an object |
| Gravity | a force that exists between any two objects that have mass |
| Inertia | an object's resistance to a change in motion |
| Newton’s laws of motion | 3 laws describing the way objects and forces are related |
| Acceleration | a change in the velocity (speed |
| Lever | simple machine effort load fulcrum |
| Wedge | simple machine used to separate |
| Wheel and axle | simple machine used to move loads |
| Pulley | simple machine used with a moveable fulcrum to lift or move loads |
| Inclined plane | simple machine with a sloped surface |
| Potential energy | Energy that an object possesses due to its position or condition |
| Kinetic energy | Energy that an object possesses due to its motion |
| Energy | The ability to do work |
