Question

What will be the average velocity for a particle revolving on a circular path of radius R for one
complete cycle of revolution?
​

Answer 1

Answer:

0

Explanation:

Average velocity = Total displacement / Total Time

#After completion 1 revolution particle come to same point from where it started. so, Displacement is 0

Average velocity = 0 / Total Time = 0

Answer 2

The average velocity of the particle on making one complete revolution along the circle is zero.

Given,

A circular path of radius R.

Number of revolution made by the particle=1.

To find,

the average velocity of the particle.

Solution:

• Average velocity of any object is defined as the ratio of the total displacement made by the body to the total time taken by the body.
• Its unit is m/sec.
• Average speed of any object is defined as the ratio of the total distance covered by the body to the total time taken by the body.

On completing one revolution along the circle of radius R, the particle returns to the same point from where it started.

Thus, the displacement made by the particle is zero.

As the displacement is zero, the average velocity will also be zero.
