Across
  1. 1. The amount of matter in an object
  2. 2. Force that opposes motion between two surfaces that are touching
  3. 4. Substances that are applied to surfaces to reduce the friction between them
  4. 6. The point in which an object appears to stay in one place.
  5. 8. Tendency of an object to not change its motion unless acted on
  6. 9. SI unit of measurement for force
  7. 12. Force of attraction between objects that have mass
  8. 13. Speed x Time
  9. 15. The rate at which velocity changes. (speed up, slow down, change direction)
  10. 17. – total distance covered in the total time.
Down
  1. 1. When an object changes position over time when compared with a reference point
  2. 3. Distance / Speed
  3. 5. The rate at which an object moves (Distance traveled in a certain time.)
  4. 7. a push or a pull
  5. 10. A measure of gravitational force exerted on an object
  6. 11. The speed of an object in a particular direction
  7. 14. Combined forces on an object
  8. 16. This is when the net force on an object is not zero
