Newton's Laws of Motion

What you need to know and show:

  • Whenever an object is seen to speed up, slow down, or change direction we know an unbalanced force acts on it.
  • For every action, there is an equal and opposite reaction.
  • The different kinds of forces and their effects on objects.
  • Balanced forces' action on an object result in no change in motion.
  • Every object exerts gravitational forces on every other object. Gravitational forces are hard to detect unless at least one of the objects has a lot of mass.
