5 Matching questions

  1. Newton's Law of Inertia
  2. Momentum (units)
  3. Static friction (units)
  4. Power (units)
  5. Impulse-Momentum Relationship
  1. a kg*m/s-amount of motion an object possesses
  2. b body will maintain a state of rest or constant velocity unless acted on by an external force that changes states
  3. c When an impulse acts on a system, the result is a change in the system's total momentum
  4. d W-rate of work production
  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. N-force that impedes motion when object is moving; level of dynamic friction is constant
  2. 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
  3. the study of bodies at rest; an object moving at constant velocity=@rest
  4. kg*m2-resistance to change in angular motion
  5. No units- resistance to change in motion

5 True/False questions

  1. Newton's Law of Accelerationan 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. Conservationboth momentum and mechanical energy are conserved

          

  3. BiomechanicsScience which studies the influence of forces on bodies

          

  4. Kinematicsthe study of bodies at rest; an object moving at constant velocity=@rest

          

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