| Term | Definition |
|---|---|
| Force | A push or pull on an object that may change the motion of the object. |
| Mass | The amount of matter in an object. |
| Weight | A measure of the force of gravity exerted on an object. |
| Net Force | The overall force exerted on an object measure in Newtons. |
| Balanced Force | Equal forces that do not cause a change in an objects motion. |
| Unbalance Force | Unequal forces that cause a change in an objects motion-speed or direction. |
| Newtons | The units used for forced. |
| Friction | A force that resists motion when two surfaces are touching each other. |
| Gravity | A force that pulls all objects that have mass toward one another. |
| Air Resistance | The frictional force air exerts against a moving object. |
| Isaac Newton | The scientist credited with the 3 laws of motion. |
| Motion | Any change in the location of an object. |
| Newtons 1st Law | An object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force. |
| Newtons | The force of an object is equal to it's mass multiplied by it's acceleration. |
| Newtons 3rd Law | For every action there is an equal and opposite reaction. |
| Inertia | An objects tendency to resist a change in motion. |
| Speed | The distance an object travels per unit of time. |
| Average Speed | The total distance an object travels divided by the total time traveled. |
| Constant Speed | Speed that remains the same or does not change. |
| Velocity | Speed in a given direction. |
| Acceleration | The rate of change of velocity which includes speeding up , slowing down, or changing direction. |
| Distance | How far an object has traveled. |
| Displacement | How far an object is away from where it started. |
| Work | Using a force to move an object |
| Position |
