Question Detail
Question
Which of the following is NOT one of the equations of motion for constant angular acceleration?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The lecture lists the three standard equations of rotation under constant acceleration. The correct formula for average angular displacement is θ = ((ωf+ωi)/2)t. Option D is missing the factor of 1/2 for the average velocity.
Hint
The lecture provides θ = ω̄ t, where ω̄ is the average angular velocity. What is the formula for the average of two values?
