| Question | Answer |
|---|---|
| Newton's First Law | An object stays stationary or in constant motion unless acted on by an outside force |
| Newton's Second Law | The strength of a force is related to its mass and acceleration F=ma. |
| Newton's Third Law | For every action there is an equal and opposite reaction. |
| Units for acceleration | m/s2 |
| Units for mass | kg |
