- 4. the energy possessed by a body
- 5. is a mechanical device that changes the direction or magnitude of a force
- 6. to the quantity of motion that an object has.
- 8. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
- 14. When two forces acting on an object are not equal in size, we say that they are
- 16. movement
- 17. the same
- 18. two forces acting in opposite directions on an object, and equal in size.
- 19. energy stored in the bonds of chemical compounds, like atoms and molecules.
- 21. a heavy or bulky thing that is being carried or is about to be carried.
- 22. the resistance that one surface or object encounters when moving over another.
Down
- 1. is a form of energy resulting from the flow of electric charge. Energy is the ability to do work or apply force to move an object.
- 2. fancy word for pushing or pulling.
- 3. is the vector sum of forces acting on a particle or body
- 7. pushing somthing away
- 9. strength or energy as an attribute of physical action or movement.
- 10. a plane inclined at an angle to the horizontal.
- 11. pulling somethig close
- 12. apply or bring to bear (a force, influence, or quality).
- 13. strenuous physical or mental exertion.
- 15. pannels that the sun give energy to
- 20. an invisible force that pulls objects toward each other.
