  • Newton's Third Law of Motion states that for every action force, there is a simultaneous reaction force thats equal in magnitude and opposite in direction.
  • F1 on 2 = F2 on 1
  • Action Force - person pushing the skateboard backwards. FBD of skateboard.
  • Reaction Force - skateboard pushing the person forward. FBD of person.
  • The forces do not cancel each other out, and they are not added together.
