PHY 101 Circular Motion Objective Question

Question

If the linear speed of an object in circular motion doubles and the radius remains constant, what happens to its angular velocity?
Options
A It is quartered.
B It is halved.
C It doubles.
Correct Answer
D It remains the same.
Correct Answer

Option C is the correct answer.

Detailed Explanation

From the relationship v = ωr, if r is constant, then ω is directly proportional to v. Therefore, if v doubles, ω must also double.

Hint

Look at the direct proportionality in the formula v = ωr.
