Question

# Identify the correct statement:

A
For a body in motion, average speed can be zero but average velocity can not be zero
B
For a body in motion, average velocity can be zero but average speed can not be zero
C
For a body in motion, both average velocity and average speed can be zero
D
For a body in motion, both average velocity and average speed can not be zero

Solution

## The correct option is B For a body in motion, average velocity can be zero but average speed can not be zeroAverage Velocity = $$\dfrac{Total\,displacement}{Total\,time}$$and Average Speed = $$\dfrac{Total\,distance}{Total\,time}$$For a moving body, total displacement can be zero but total distance can never be zero.So, Average Velocity can be zero but Average Speed can never be zero.Physics
