Across
- 1. force that works against and tries to prevent an object from moving or stop a moving object
- 4. An object at rest will stay at rest, and an object in motion will stay in motion at constant rate,unless acted upon by an unbalanced force
- 6. force that slows down a moving object
- 8. the amount of matter in an object
- 11. Opposite charges attract, Like Charges repel
- 14. holds the protons and neutrons in the nucleus together
- 15. A body acted on by a force will accelerate such that force equals mass times acceleration
- 16. upward push in spite the pull of gravity
- 18. attractive force between all objects with mass
- 19. For every action there is an equal and opposite reaction
- 20. result to change in the state of motion of the body on which it acts
- 21. the force that gravity exerts upon an object
Down
- 2. non contact forces
- 3. force applied to an object by a person or another object
- 5. forces that keep a stationary object at rest
- 7. the energy possessed by a body by virtue of its position relative to others
- 9. allows interaction within the atom resulting to radioactive decay of some nuclei
- 10. contact forces
- 12. change in position of an object with respect to time
- 13. Parallel to surface, opposing direction of motion
- 17. acts and opposes on objects traveling on air
