  1. Statics
  2. Pressure (units)
  3. Kinetic Friction (units)
  4. Mass (units)
  5. Strain Energy (units)
  1. a kg-quanitity of matter composing a body
  2. b N-force that impedes motion when object is moving; level of dynamic friction is constant
  3. c the study of bodies at rest; an object moving at constant velocity=@rest
  4. d 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
  5. e N/m2-Force distributed over a given area

5 Multiple Choice Questions

  1. an applied force causes an acceleration of the body; 1. with a magnitude proportional to the force 2. in the direction of hte force 3. inversely proportional to the mass
  2. W-rate of work production
  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. Science which studies the influence of forces on bodies

5 True/False Questions
