Angular vs. Linear variables
Two objects on a turntable spin at a constant rate. What (if anything) is the same for the two objects?
- They have the same speed, but different velocities. (1/31) (3%)
- They have the same speed and the same velocity. (0/31) (0%)
- The have the same angular speed, but different angular velocities. (10/31) (32%)
- They have the same angular speed and the same angular velocity. (10/31) 32%)
- Both 1 and 3 (4/31) (13%)
- Both 1 and 4 (2/31) (6%)
- Both 2 and 3 (0/31) (0%)
- Both 2 and 4 (2/31) (6%)
- None of the above. (2/31) (6%)
What about their accelerations?
- Their accelerations have the same magnitude, but the red one has a larger angular acceleration. (1/32) (3%)
- Their accelerations have the same magnitude, but the blue one has a larger angular acceleration. (2/32) (6%)
- They have the same angular accelerations, but the red one has a larger magnitude acceleration. (21/32) (66%)
- They have the same angular accelerations, but the blue one has a larger magnitude acceleration. (3/32) (9%)
- Both the acceleration and the angular acceleration equal zero for both objects.(4/32) (12%)
- None of the above. (1/32) (3%)
