Question
Read the statement below carefully and state, with reason, if it is true or false:
The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector.
Options
True
False
Solution
This statement is True.
Explanation:
In uniform circular motion (UCM), the direction of the acceleration vector points towards the centre of the circle. However, it constantly changes with time. The average of these vectors over one cycle is a null vector.
