5 Matching questions

  1. Ground Reaction Force (units)
  2. Power (units)
  3. Pressure (units)
  4. Static friction (units)
  5. Mass (units)
  1. a kg-quanitity of matter composing a body
  2. b N/m2-Force distributed over a given area
  3. c N-force that impedes motion when object is static; amount of static friction varies with amount of applied force
  4. d W-rate of work production
  5. e 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 Multiple choice questions

  1. N-push or pull acting on a body or a system; has magnitude and direction
  2. When an impulse acts on a system, the result is a change in the system's total momentum
  3. 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
  4. study of biological systems from a mechanical perspective
  5. the study of bodies at rest; an object moving at constant velocity=@rest

5 True/False questions

  1. Dynamicsthe study of bodies at rest; an object moving at constant velocity=@rest


  2. Conservationboth momentum and mechanical energy are conserved


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


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


  5. Moment of Force (units)Nm-rotary force (drawn as a vector, but as an arc) M=Fd_I
