Across
  1. 3. - When two objects rub together
  2. 4. - the action-reaction pair of forces acting at each end of a string, a rope, chain, or similar object, or by each end of a rod,
  3. 5. - state of a body that moves freely in any manner in the presence of gravity
  4. 8. - quantity that designates how fast and in what direction a point is moving
  5. 11. - the sum of all the forces acting on an object
  6. 14. - an imperial unit of mass or weight measure
  7. 16. - the location of an object at any given time
  8. 18. - the force needed to accelerate one kilogram of mass at the rate of one meter per second squared
  9. 19. - the act of an object speeding up
  10. 21. - an object will remain at rest or in unchanging motion unless acted on by some external force
  11. 22. - an influence that can cause an object to change its velocity
  12. 23. - when all the forces on a object are exactly in balance so that it does not move
  13. 24. - strength or force gained by motion or by a series of events
  14. 25. - the acceleration gained by an object due to gravitational force
  15. 26. - an object will stay at rest unless compelled to change its state by the action of a force
  16. 27. - How fast or slow an object is going
  17. 28. - the movement between objects that slide against each other
  18. 29. - a force that keeps an object at rest
Down
  1. 1. - Two or more objects’ total momentum remains constant unless an external force is applied
  2. 2. - a measurement of how fast an object is moving at that particular moment
  3. 6. - a quantity that has two independent properties: magnitude and direction
  4. 7. - When two forces are the same strength but act in opposite direction
  5. 9. - for every action there is an equal and opposite reaction
  6. 10. - When an object travels the same distance in the same period of time
  7. 12. - the force applied in one direction is greater than the force applied in the opposite direction
  8. 13. - how steep a line is
  9. 15. - an increase in length when pulled
  10. 17. - net force is equal to mass times acceleration(F = ma)
  11. 19. - How fast or slow an object is on average
  12. 20. - Reduction in the volume of a substance due to pressure
