5 True/False questions

  1. Impulse-Momentum RelationshipWhen an impulse acts on a system, the result is a change in the system's total momentum

          

  2. DynamicsThe study of bodies in motion

          

  3. Free Body DiagramN-push or pull acting on a body or a system; has magnitude and direction

          

  4. Center of Mass (units)m-point of application of the GRF

          

  5. Kinetic Energy (units)J-special form of potential energy; when an object is deformed its tores strain energy which is returned as KE when the object returns to the origional shape
