PHY 101 Circular Motion Objective Question
Take CBT

Question

What is the definition of angular acceleration (α)?
Options
A The total change in angular displacement.
B The rate of change of linear velocity.
C The rate of change of angular velocity.
Correct Answer
D The average of initial and final angular velocities.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture states that angular acceleration occurs when the rate of rotation changes, given by α = (ωf - ωi)/t, which is the rate of change of angular velocity.

Hint

This is the rotational analog of linear acceleration, which is the rate of change of linear velocity.
