Angular vs. Linear variables

Two objects on a turntable spin at a constant rate. What (if anything) is the same for the two objects?

  1. They have the same speed, but different velocities. (1/31) (3%)
  2. They have the same speed and the same velocity. (0/31) (0%)
  3. The have the same angular speed, but different angular velocities. (10/31) (32%)
  4. They have the same angular speed and the same angular velocity. (10/31) 32%)
  5. Both 1 and 3 (4/31) (13%)
  6. Both 1 and 4 (2/31) (6%)
  7. Both 2 and 3 (0/31) (0%)
  8. Both 2 and 4 (2/31) (6%)
  9. None of the above. (2/31) (6%)














What about their accelerations?

  1. Their accelerations have the same magnitude, but the red one has a larger angular acceleration. (1/32) (3%)
  2. Their accelerations have the same magnitude, but the blue one has a larger angular acceleration. (2/32) (6%)
  3. They have the same angular accelerations, but the red one has a larger magnitude acceleration. (21/32) (66%)
  4. They have the same angular accelerations, but the blue one has a larger magnitude acceleration. (3/32) (9%)
  5. Both the acceleration and the angular acceleration equal zero for both objects.(4/32) (12%)
  6. None of the above. (1/32) (3%)
