Gravity and Newton
| Question | Answer |
|---|---|
| a force of attraction between objects | gravity |
| a force that opposes motion through air | air resistance |
| an object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force acts on it | Newton's 1st law |
| mass multiplied by acceleration equals | force |
| rate at which objects fall due to gravity | 9.8m/s/s |
| an objects resistance to change motion | inertia |
| another name for Newton's 1st law | Law of Inertia |
| gravity mulitipled by time equals | change in velocity |
| all objects will fall at the same rate if there is no | air resistance |
| when the only force acting on an object is gravity | free fall |
| when gravity and air resistance are equal | terminal velocity |
| acceleration depends on the force and mass of an object | Newton's 2nd law |
| every force has an equal and opposite force | Newton's 3rd law |
| when objects collide the momentum stays the same | Law of momentum |
| mass mulitplied by velocity equals | momentum |
| m/s | velocity |
| m/s/s | acceleration |
| Newton | force |
| kg | mass |
| kg mulitiplied by m/s E | momentum |
