  • What force is being used in this picture?
    Push force
  • True or False, you can SEE a force.
    False
  • Will friction make an object go faster or slower?
    Slower
  • What is Isaac Newton's Second law of Motion?
    For every action there is an equal and opposite reaction
    For every action there is an unequal and opposite reaction
    An object at rest will stay at rest unless acted upon
    The acceleration of an object depends on the force and mass
  • What does balanced force mean? A force is equal and in the opposite direction OR a force is equal and in the same direction.
    A force is equal and in the opposite direction
  • Which ball has more friction? The top ball or the bottom ball?
    Top ball
  • What does equal force mean? The same OR different
    the same force

    A
  • What is an example of a sliding force?
    ...
  • An unbalanced force is when forces are not equal in size. True OR false
    True
  • What is Isaac Newton's Third law of Motion?
    The acceleration of an object depends on the force and mass
    For every action there is an unequal and opposite reaction
    For every action there is an equal and opposite reaction
    An object at rest will stay at rest unless acted upon
  • What is an example of a Kinetic force?
    ...

    When 2 objects touch
  • Where is the force the greatest? With the 2 boys or with the 1 boy?
    The 2 boys
  • What is Isaac Newton's First law of Motion?
    The acceleration of an object depends on the force and mass
    For every action there is an unequal and opposite reaction
    For every action there is an equal and opposite reaction
    An object at rest will stay at rest unless acted upon
