  • If you move a heavy object across the floor, why won’t it move right away?
    When you apply horizontal force, the floor applies frictional force
  • The 3rd law is related to the push and pull of an object. (True or False)
    True
  • If you reduce the friction when you move something, which occurs?
    You don't have to use as much force
  • The amount of force on the first object does not equal the amount of force on the second object ( True or False).
    False
  • If you saw an action of someone jumping up on a trampoline, what would the reaction be?
    They come down
  • The third law always comes how?
    In pairs
  • Newton’s 3rd law of motion states which?
    For every action there is an equal and opposite reaction
  • If the boxer gives the bag 5 pounds of force, he will receive how much force back?
    5 pounds
  • When rockets from NASA move downward, what happens to the rockets according to Newton's 3rd law?
    They move up
  • If a bowler used 20 pounds of force to roll a ball down an alley, what amount of force would the bowling pins receive?
    20 pounds
  • The forces of action and reaction are which?
    Always equal
  • When the object that you are moving across the floor is in motion, what is this called?
    Sliding friction
  • Sliding friction is the same sensation you get when you rub both hands together (True or False).
    True
  • The less friction you have the more energy you use (True or False).
    False
  • What happens when a cannon ball shoots forward?
    The cannon moved backward
  • If the boxer hits a bag with 50 pounds of force, the bag will receive how many pounds of force back?
    50 pounds
  • What causes a shuttle to launch?
    The force of the action and reaction together
  • If a small rock was pushed into a lake, why would there not be a big splash?
    It is not an equal and opposite reaction
  • What reaction would you get if a ball were rolling on top of a table?
    It will roll down to the floor
  • Which reaction happened when the male stepped off the boat?
    The boat moved backward
