Across
  1. 2. of Force and Acceleration/A total force acting on an object to accelerate in the opposite direction.
  2. 7. that resists motion between 2 touching surfaces.
  3. 8. Force/2 equal forces that cancel each other because they are acting in opposite directions.
  4. 9. of Inertia/Object will stay at rest or will keep moving in a straight line unless acted on by an outside force to make it stop.
  5. 10. traveled divided by the time needed to travel.
  6. 12. is pulling something above their head.
  7. 13. or pull on an object.
  8. 15. Force/Mass force of an object divided by the mass of an object.
  9. 16. Resistance/Friction of air.
Down
  1. 1. you go to the moon,this will not change! Amount of matter in an object.
  2. 3. Plane/Somebody pushing something up a ramp.
  3. 4. Difference between the final position and the initial position if motion is in a straight line.
  4. 5. to resist a change in motion.
  5. 6. Force/An objects motion will change if an unbalanced force acts on it.
  6. 11. of the strength of earths gravitational pull ex: When you go to the moon, this becomes lighter.
  7. 14. and Axle/something such as a bike.
