5 Matching questions

  1. Free Body Diagram
  2. Center of Mass (units)
  3. Moment of Inertia (units)
  4. Biomechanics
  5. Static friction (units)
  1. a kg*m2-resistance to change in angular motion
  2. b study of biological systems from a mechanical perspective
  3. c m-point around which a body's mass is equally balanced in all directions. Point of application of the weight force
  4. d sketch of a system of interst with the surrounding environmetn/segments removed; and all of the forces drawn on the body. An important first step in the mechanical solutions since it helps to visualize all the forces acting on the system
  5. e N-force that impedes motion when object is static; amount of static friction varies with amount of applied force

5 Multiple choice questions

  1. J-capacity to do work; "energy of position"
  2. m- length of perpendicular line from the line of force through the axis of rotation
  3. Nms-area under the moment-time curve
  4. N-3D forces measured at the ground; represent the summation fo acceleration (F=ma) of all body segments. Point of application is the COP.
  5. the study of bodies at rest; an object moving at constant velocity=@rest

5 True/False questions

  1. Work (units)J-force multiplied by displacement of system


  2. Center of Pressure (units)m-point of application of the GRF


  3. Power (units)W-rate of work production


  4. Newton's Law of Reactionfor every action, there is an equal and opposite reaction


  5. MechanicsScience which studies the influence of forces on bodies
