  1. 7. A noncontact force that acts over a distance and pulls all objects towards each other.
  2. 11. The tendency of an object in motion to stay in motion or of an object at rest to stay at rest.
  3. 12. Energy of motion.
  4. 13. A force that opposes the motion of one object moving past another.
  5. 14. How fast an object’s position changes over time. Distance ÷ Time
  6. 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

  1. 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. 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. 3. A push or pull that one exerts on a system’s state of rest or uniform motion. Example: pedaling a bicycle
  4. 4. Energy that is stored in the position or condition of an object. Examples include: gravitational potential, elastic potential, chemical potential
  5. 5. The change in speed or direction of an object. Change in speed ÷ Time
  6. 6. A force that occurs when one object touches another.
  7. 8. A change in an object’s position in respect to time and in comparison to other objects
  8. 9. The ability to do work or to change an object. Units of energy are called joules (J).
  9. 10. The force between two magnets or between a magnet and certain metals. This force can push or pull.
