Question
A point on a rotating disk moves from one position to another, sweeping out an angle. What is the term for this measure of rotation?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The lecture defines angular displacement as the measure of the amount of rotation a body undergoes, denoted by the angle θ. Angular acceleration is the rate of change of angular velocity, while the arc length is the distance along the path, s.
Hint
Think of the Greek letter θ, which is used to represent this quantity.
