Detailed Solution

Suppose a boy is enjoying a ride on a merry-go-round which is moving at a constant speed of

10 m / s

. It implies that the boy is moving with uniform velocity.
The rate of change in an object's position with regard to time and a frame of reference is known as its velocity. A body is said to have uniform velocity when it moves through space at a speed that causes equal distances to be covered in equal amounts of time.
Velocity is a vector quantity, and a change in velocity is due to a change in magnitude, direction, or both. An object moving with constant speed has a uniform velocity.
