Across
- 4. the vector sum of all the forces that act upon an object
- 5. mass x acceleration
- 9. the amount of matter in an object
- 11. tendency of an object to resist a change in motion
- 12. Unit for weight
- 13. what stays the same in an experiment
- 14. measure of the gravitational force exerted on an object
- 15. Forces that produce a nonzero net force, which CHANGES an object's motion
- 17. Stored energy
Down
- 1. amount of space an object takes up
- 2. what you change in an experiment
- 3. forces acting on an object that combine and form a net force of zero
- 6. the resistance that one surface or object encounters when moving over another
- 7. used to help you solve force, mass, and acceleration problems
- 8. energy of motion
- 10. distance/time
- 16. the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change
