A conceptual question:
A car travels in a circular path with constant speed. Which of the following quantities is constant and non-zero for this car?
a.) linear velocity
b.) angular velocity
c.) centripetal acceleration
d.) angular acceleration
e.) total acceleration
The answer is b.) angular acceleration, but why? I figured it would have to be linear velocity, because ang velocity=v/r and isn't the r of a circular path going to be constant? So how can angular velocity be constant without the linear velocity constant?
