A change in the velocity of an object always indicates change in speed. Comment.

Or, the velocity of a body is continuosly changing. Can its speed remain constant?

A change in the velocity of an object does not always indicate the change in speed. A change in the velocity occurs if either its magnitude changes or direction changes or both. If the change in velocity occurs only due to the change in direction, then the speed remains constant.
