Across
- 3. Total distance divided by total time
- 6. How much matter is in an object
- 7. A force caused by 2 objects rubbing together

Down
- 1. Rate at which velocity changes
- 2. An object or place that you can use to tell if an object is moving
- 4. When net force of an object is zero; objects motion doesn't change
- 5. Friction caused by air and force that pushes upward on falling object
