Across
- 7. A noncontact force that acts over a distance and pulls all objects towards each other.
- 11. The tendency of an object in motion to stay in motion or of an object at rest to stay at rest.
- 12. Energy of motion.
- 13. A force that opposes the motion of one object moving past another.
- 14. How fast an object’s position changes over time. Distance ÷ Time
- 15. A force that has to do with the charge an object carries. Opposite charges attract and same charges repel. Example: static electricity in clothes or hair
- 16. A push or pull that causes an object to move, stop, or change direction.
Down
- 1. Forces that do not add up to zero. They change the motion of an object.The greater force determines the direction of motion.
- 2. Forces that act on an object without changing its motion. Balanced forces often point in opposite directions and always add up to zero.
- 3. A push or pull that one exerts on a system’s state of rest or uniform motion. Example: pedaling a bicycle
- 4. Energy that is stored in the position or condition of an object. Examples include: gravitational potential, elastic potential, chemical potential
- 5. The change in speed or direction of an object. Change in speed ÷ Time
- 6. A force that occurs when one object touches another.
- 8. A change in an object’s position in respect to time and in comparison to other objects
- 9. The ability to do work or to change an object. Units of energy are called joules (J).
- 10. The force between two magnets or between a magnet and certain metals. This force can push or pull.
