Across
  1. 2. forces Forces act on an object without changing its motion (constant velocity or at rest) and the total forces add up to be zero.
  2. 7. A change in an object’s position
  3. 10. A force between surfaces that slows objects or stops them from moving.
  4. 11. resistance Friction between the air and a moving object
  5. 12. The ability to do work
  6. 13. Potential Energy Potential energy in an object due to its elasticity (when it’s being stretched or compressed).
  7. 14. A noncontact force that pulls all objects towards each other.
  8. 15. The position of an object
  9. 16. force Forces that occur without objects touching
  10. 17. Energy The energy an object has because it is moving.
  11. 18. How fast an object’s position changes over time at any given moment
Down
  1. 1. Potential Energy Potential energy when an object is above a surface (in a high position).
  2. 3. A change in velocity over time
  3. 4. The speed and direction of an object
  4. 5. Energy The energy is stored in an object and can be used later.
  5. 6. force Forces that occur when one object touches another
  6. 8. The tendency of an object in motion to stay in motion or of an object at rest to stay at rest.
  7. 9. forces Forces that do not add up to zero and can affect an object’s motion (speed, direction, or both).
  8. 10. A push or pull
