PHY 101 Circular Motion Objective Question

Question

Tangential acceleration (aT) is a measure of the rate of change of which quantity?
Options
A Angular velocity
B Direction of motion
C Magnitude of linear velocity
Correct Answer
D Radius of the path
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture introduces tangential acceleration when linear velocity changes from vi to vf. It is defined as aT = (vf - vi)/t, which is the rate of change of the magnitude of linear velocity (speed).

Hint

This acceleration is 'tangential' because it acts along the direction of motion, changing the object's speed.
