Across
- 1. The force applied to an object
- 10. Force that opposes motion
- 12. No momentum is lost or gained in collisions
- 13. Force that acts across empty space
- 15. Objects collide and bounce apart completely
- 18. An object at rest stays at rest, and an object in motion stays in motion unless an outside force acts on the object.
- 20. Force between objects with electric charge
- 21. Acceleration is directly proportional to the net force acting on it
- 22. Representation of both the magnitude (strength) and direction of a force
- 24. The change in momentum of an object
- 25. An objects resistance to changing its motion
- 27. The equal and opposite force the object applies back
- 28. Objects collide and some kinetic energy is lost to heat, sound, or deformation
- 30. For every action, there is an equal and opposite reaction
Down
- 2. Objects collide and stick together after impact
- 3. Objects begin at rest or moving together, then separate
- 4. Sum of all forces acting on an object
- 5. Force that surfaces exert on objects resting on them
- 6. Force when two objects are physically touching
- 7. A force directly applied to an object
- 8. gravitational force acting on mass
- 9. The attractive force between any two objects with mass
- 11. The quantity of motion an object has
- 14. A force transmitted through strings, ropes, cables, or chains
- 16. Visual representation of all forces acting on an object
- 17. Force between magnetic materials
- 19. Cause of an object to start moving, stop moving, or change direction.
- 23. Discovered three laws about how things move
- 26. Force of objects moving through the air
- 29. Amount of matter in an object
