Across
  1. 6. the rate at which velocity changes; calculated by diving change in velocity by the time
  2. 7. speed in a given direction
  3. 9. the effect of a force acting on an object over time. Calculated by multiplying mass by the change in velocity
  4. 12. a result of a force moving an object a certain distance
  5. 13. the constant velocity of a falling object when the force of air resistance equals the force of gravity
  6. 16. the acceleration of an object is equal to the net force acting on it divided by the objects mass
  7. 18. the two equal but opposite forces that exist when two systems act on each other
  8. 19. two equal forced acting in opposite directions on an object
  9. 21. the state of motion of an object does not change as long as the net force acting on the objects is zero
  10. 23. a force which is applied to an object by a person or another object
  11. 24. two or more forces that are not equal and opposite of one another; can cause change in motion
Down
  1. 1. whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
  2. 2. a push or pull that acts on an object
  3. 3. speed and direction of an object at a particular instant
  4. 4. the tendency of an object to resist a change in its motion
  5. 5. law stating that the total momentum of a group of objects stays the same unless outside forces act on the objects
  6. 8. distance and direction of an objects change in position from the starting point
  7. 10. the product of an objects mass and velocity
  8. 11. a physical quantity that has magnitude but no direction
  9. 14. the state of an object when not it is not in motion
  10. 15. a physical quantity that has both magnitude and direction
  11. 17. a system of objects that are not moving with respect to one another
  12. 20. the rate which work is done
  13. 22. the motion of an object toward the earth because of gravity
