Across
- 3. a push or pull exerted on an object
- 5. a region of space in which every point has a physical quantity, such as a force
- 7. the ability to cause change, measured in joules
- 9. force a push or a pull on one object by another object that is touching it
- 10. that opposes the sliding motion between two touching surfaces
- 13. material,such as a copper wire, through which electrons can move easily
- 14. the attractive or repulsive force between electric charges and magnets
- 16. a closed path that electric current flows
Down
- 1. SI unit of electric current
- 2. attractive force between two objects that depends on the masses of the objects and the distance between them
- 4. energy energy a moving object has because of its motion
- 6. of conservation of charge states that charge can be transferred from one object to another but it cannot be created or destroyed
- 8. the net movement of electric charges in a single direction, measured in amperes
- 11. the tendency of an object to resist a change in its motion
- 12. SI unit of work and energy
- 15. material in which electrons and thermal energy are not able to move easily
