| Question | Answer |
|---|---|
| When is a force balanced? | when there is a constant velocity |
| When is a force unbalanced? | when there is not a constant velocity |
| How do you combine forces? | with addition |
| 3 types of friction | fluid, rolling, sliding |
| 1st law of motion | An object in motion/rest will stay at motion/rest unless acted on by an outside force |
| 2nd law of motion | F = m x a |
| 3rd law of motion | for every action, there is an equal and opposite reaction |
| formula for mass | m = f/a |
| formula for weight | w = m x g |
| 2 conditions that cause the force of gravity to change | distance apart, mass |
