#### 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.
2. They have the same speed and the same velocity.
3. The have the same angular speed, but different angular velocities.
4. They have the same angular speed and the same angular velocity.
5. Both 1 and 3
6. Both 1 and 4
7. Both 2 and 3
8. Both 2 and 4
9. None of the above.

What about their accelerations?

1. Their accelerations have the same magnitude, but the red one has a larger angular acceleration.
2. Their accelerations have the same magnitude, but the blue one has a larger angular acceleration.
3. They have the same angular accelerations, but the red one has a larger magnitude acceleration.
4. They have the same angular accelerations, but the blue one has a larger magnitude acceleration.
5. Both the acceleration and the angular acceleration equal zero for both objects.
6. None of the above.
