  • A chair with no one sitting in it is an example of an object a rest.
    True
  • A pillow on a bed is an example of an object in motion.
    False
  • If a ball gets kicked and is not longer at rest, how does it move?
    In the direction of the greater force
  • When two or more forces act on an object the sum will be what?
    The sum of all forces acting in that direction
  • When net forces cancel each other out it creates what?
    A balanced force
  • When a ball is kicked it would be in motion forever if it weren't for which?
    Friction
  • If the net force is zero what happens?
    A balanced force
  • If a body is at rest how will it start moving?
    In the direction of the forces
  • What is a net force?
    Adding up all the forces acting on any object and the resulting sum is the net force
  • The object with an unbalanced force will move how?
    In the direction of the stronger force.
  • When does a net force equal zero?
    When forces cancel each other out.
  • If the forces don't equal zero than what happens?
    An unbalanced force
  • As an object moves in the direction of the net force, what happens?
    Speed increases
  • The object with an unbalanced force will move how?
  • Also, Newton’s first law states that if an object is already in motion it will stay that way until what?
    Acted on by an unbalanced force
  • If an object is in motion and its net force is NOT zero, the object will experience what?
    A change in motion
  • A bowling ball on a self is a balanced force.
    True
  • When two forces at in opposite directions, how is the net force calculated?
    By subtracting the forces
  • When an object is at rest what is its net force
    Zero
  • If a body is in constant motion, the motion will do what?
    Increase in the direction of the net force
  • Friction always acts in a direction opposite of what?
    Motion
  • If two forces are acting on a car that is not moving, what happens?
    The car moves in the direction of the greater force.
