Across
- 5. unequal forces acting on an object causing it to move in a direction
- 6. The combination of all forces acting on an object
- 8. f= MA;Heavier objects take more force to move
- 9. A place or object used for comparison to determine if an object is in motion
- 11. A push or pull
- 12. law of intertia;Object will continue to move until something stops them
- 15. Distance/time
- 16. A measure of how much matter is an object
- 17. The rate at which velocity changes
Down
- 1. equal forces acting on an object in opposite directions
- 2. action/reaction; Every action has an opposite and equal reaction
- 3. A force that opposes motion between two surfaces that are in contact
- 4. A force that moves rocks and other materials downhill
- 7. An object's change in position relative to a reference point
- 10. Moving at a steady rate over time
- 13. resistance to change in motion
- 14. speed in a given direction
