Question

As you look at the side of the wheel, you can see it spinning clockwise. What are the directions of the angular velocity, and angular momentum?
If the torque is applied to the rim, causing the wheel to slow down, what are the directions of the torque and the angular acceleration?

Answer 1

Answer:

The direction of angular velocity and angular momentum are perpendicular to the plane of rotation. Using the right hand rule, the direction of both angular velocity and angular momentum is defined as the direction in which the thumb of your right hand points when you curl your fingers in the direction of rotation.
