- 1. the speed of something in a given direction.
- 2. an acceleration = to 7.8 m/s squared
- 4. a force that consists of equal and opposite forces
- 5. a force that consists of unequal forces
- 7. also known as the law of intertia. An object at rest will stay at rest and an object at motion will stay in motion unless acted upon by an unbalanced force.
