Presentation Transcript

  1. The friction force is proportional to the surface area of the object in question. • True • False

  2. Kinetic coefficient forces are less than the largest possible static friction force. • True • False

  3. If it takes a force F to displace a spring from equilibrium a distance X, how much force will it take to displace the spring a distance 2X from equilibrium? • F2 • 2F • F/2 • Sqrt(F)

  4. A spring is compressed from equilibrium. In which direction will Fspr point? • Towards equilibrium • Away from equilibrium • Towards displacement • Opposite displacement

  5. Your weight will change when moving in a horizontal circle at a constant speed. • True • False

  6. Where will you weigh the most when moving at a constant speed in a vertical circular path? • Top of circular path • Bottom of Circular path • Midway between top and bottom on the path • Weight does not change!
