         Today we are going to discuss:
         Chapter 5:
         Force, Mass:  Section 5.1
         Weight—the Force of Gravity; and the Normal 
           Force/Tension: Section 5.2-5.4
          Newton’s First Law of Motion: Section 5.6
          Newton’s Second Law of Motion: Section 5.5
         Free-Body Diagram: Section 5.7

         Transition from Kinematics to Dynamics
                     It’s time to complicate life 
         In Kinematics we studied
                       HOW things move
                   Motion         Forces
         Now in Dynamics we will study 
                       WHY  things move
                   Motion         Forces

                      Force
    A force was introduced to describe interactions between two objects
                  A force is a push or pull 
             push             pull
    Force has magnitude and direction: VECTOR! To quantify a push or pull, we need 
    to specify both magnitude and a direction.
            An object at rest needs a force to get it moving 
              A moving object needs a force 
                to change its velocity
