Across
- 2. any physical quantity that is defined by size and direction
- 4. process by which a magnetized or electrically charged object produces magnetism, an electric charge, or an electric voltage in another object without being in contact with it created energy without being in contact
- 8. the more force in an object, the more it accelerates
- 11. the speed and direction of motion
- 13. wave goes through an object but changes direction

- 24. quantity of motion
- 26. the force that resists motion of one object rubbing against another
- 28. a force pulling outward from the center of rotation
- 29. a flat surface which has a slope
- 32. distance, when an object travels in the opposite direction of the beginning of path
- 33. when the acceleration of an object is non-changing
- 34. material that resists electron flow
- 35. states that the ratio of potential difference to current is constant relationship between voltage and current
- 36. the tendency of objects to resist changes in speed or direction of motion
- 42. a force that acts from one part of a system on another part of the same system
- 43. fall an object is free-falling when only gravity is the force pulling it down
- 44. the complete path that an electric current travels along the path energy goes through
- 45. every action has an equal and opposite reaction
- 46. an object with unchanging speed
- 47. Kirchhoff's rule that the algebraic sum of the currents at any branch point or junction in a circuit is zero the sum of currents in a circuit is zero
- 49. a force pulling inward toward the center of rotation
- 50. the electrons only have one path to follow through the current is the same at every point in the circuit; there is only one path for the energy to follow
- 51. refers to size of a vector
Down
- 1. an object initially propelled by a force outside itself and keeps moving
- 3. motion, motion which a nonmoving person sees, but the moving person does not see
- 5. a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy
- 6. a constant pull of gravity
- 7. an attractive force between two objects in the universe
- 9. a quantity that has a size or magnitude only
- 10. friction which keeps things still
- 12. Kirchhoff's states that the sum of the emf values in any closed loop is equal to the sum of the potential drops in that loop the amount of a closed loop is that of the same as the potential droops in the loop
- 15. the time needed for 1 wavelength to pass
- 16. near the surface of the earth, all objects fall with constant acceleration
- 18. a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
- 19. an object moving back along the direction of space
- 20. measure of how fast velocity is changing; time rate of change
- 21. the force of friction when two objects are rubbing against each other in motion
- 23. Inertia-objects at rest tend to stay at rest and objects in motion tend to stay in motion

- 39. Push or pull
- 40. the energy of an object by virtue of its motion
- 41. the basic unit of a chemical element
- 48. force times distance; work is energy
