  1. 3. The resistance that one surface or object encounters when moving over another
  2. 5. The state of being stretched tight.
  3. 8. of conservation of momentum In an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied
  4. 12. If any given physical situation is analyzed in terms of the individual forces that are acting upon an object, then those individual forces must add up as vectors to the net force.
  5. 16. Downward movement under the force of gravity only.
  6. 18. friction The resistance created by any two objects when sliding against each other
  7. 19. The sum of all the forces acting on an object.
  8. 22. Decrease in volume of any object or substance resulting from applied stress.
  9. 23. The acceleration gained by an object due to gravitational force.
  10. 24. Strength or energy as an attribute of physical action or movement.
  11. 26. A quantity that has both magnitude and direction.
  12. 27. law An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force
  13. 28. The rate of change of velocity per unit of time.
Down
  1. 1. tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless acted on by a force to cause a change in speed or direction.
  2. 2. A measurement of mass in motion
  3. 4. Forces that are not equal in magnitude and may or may not act in the same direction
  4. 6. For every action, there is an equal and opposite reaction
  5. 7. A surface of which one end or side is at a higher level than another; a rising or falling surface.
  6. 9. The total distance traveled by the object divided by the elapsed time to cover that distance.
  7. 10. speed When the speed of an object remains the same - it does not increase or decrease
  8. 11. When two forces of the same strength but acting in opposite direction
  9. 13. The speed of an object at a particular moment in time.
  10. 14. A force that keeps an object at rest.
  11. 15. A part that is added to something to enlarge or prolong it; a continuation
  12. 17. The speed of something in a given direction.
  13. 20. A unit of weight in general use equal to 16 oz. avoirdupois (0.4536 kg).
  14. 21. The rate at which someone or something can move or operate.
  15. 25. A state in which opposing forces or influences are balanced.
  16. 29. The SI-derived unit used to measure force
