5 Matching questions

  1. Newton's Law of Inertia
  2. Moment of Force (units)
  3. Free Body Diagram
  4. Ground Reaction Force (units)
  5. Weight (units)
  1. a Nm-rotary force (drawn as a vector, but as an arc) M=Fd_I
  2. b body will maintain a state of rest or constant velocity unless acted on by an external force that changes states
  3. c N-3D forces measured at the ground; represent the summation fo acceleration (F=ma) of all body segments. Point of application is the COP.
  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-amount of gravitational force exerted on a system (always points downwards, point of application is always the COM)

5 Multiple choice questions

  1. J-capacity to do work; "energy of motion"
  2. m-point of application of the GRF
  3. m-point around which a body's mass is equally balanced in all directions. Point of application of the weight force
  4. the study of bodies at rest; an object moving at constant velocity=@rest
  5. kg*m/s-amount of motion an object possesses

5 True/False questions

  1. Kinematicsdescription of motion w/o regards to it cause; displacement, velocity, and acceleration


  2. Power (units)J-force multiplied by displacement of system


  3. BiomechanicsScience which studies the influence of forces on bodies


  4. Force (units)J-force multiplied by displacement of system


  5. Inertiadescription of motion w/o regards to it cause; displacement, velocity, and acceleration
