1 [©2008 RJ Bieniek] N EWTON S T HIRD L AW OF M OTION Learning Objectives After you complete the homework associated with this lecture, you should be able to: Describe the meaning and application of Newton’s Third Law of Motion (action-reaction law). Use tilted coordinated systems when appropriate to analyze forces and accelerations, especially on inclined planes. Determine the common acceleration magnitude of connected objects, particularly when they are moving in different directions. 2 [©2008 RJ Bieniek] N EWTON S T HIRD L AW Common version : For every action there is an equal but opposite reaction. Better version : If a force on object A produced by object 2 is F P A by 2 , then there is a force F P 2 by A on 2 produced by A that is equal-in-magnitude but opposite-in-direction to F P A by 2 . F P 2 by A = S F P A by 2
