Force & Motion Vocab
Newtons Laws of Motion
| Term | Definition |
|---|---|
| Inertia | the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an outside force. |
| Force | A push or pull on an object |
| Mass | The amount of matter in an object |
| Acceleration | The rate at which an object changes velocity |
| Newton's First Law | An object at rest will remain at rest and an object in motion will remain in motion unless or until acted on by an outside, unbalanced force. |
| Newton's Second Law | The acceleration of an object is dependent upon the mass of the object and the force exerted on it. |
| Newton's Third Law | For every action there is an equal and opposite reaction |
| Deceleration | A decrease in the speed of an object (slowing down) |
| Exert | To apply a force |
| Unit of measurement for Force | Newtons (N) |
| Unit of measurement for Mass | kilograms (kg) or grams (g) |
| Unit of measurement for Speed | meters per second (m/s) |
| Unit of measurement for Velocity | meters per second (m/s) |
| Unit of measurement for Acceleration | meters per second per second (m/s^2) |
| Formula for Force | F=MxA |
| Formula for Mass | M=F/A |
| Formula for Acceleration | A=F/M |
| Formula for Distance | D=SxT |
| Formula for Speed | S=D/T |
| Formula for Velocity | V=D/T |
| Formula for Time | T=D/S |
| Newton's 1st Law is also known as.... | the law of intertia |
| Newton's 2nd Law is also known as..... | the law of force & acceleration |
| Newton's 3rd Law is also known as.... | the law of action/reaction |
