#### 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.
- They have the same speed and the same velocity.
- The have the same angular speed, but different angular velocities.
- They have the same angular speed and the same angular velocity.
- Both 1 and 3
- Both 1 and 4
- Both 2 and 3
- Both 2 and 4
- None of the above.

What about their accelerations?

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