Draw a diagram to show the motion of a body whose speed remains constant but velocity continuously changes.
(N/A) Uniform circular motion is an example of motion where the speed of the body remains constant,but its velocity changes continuously due to the change in the direction of motion at every point along the circular path.
The diagram below illustrates this motion,where $v$ represents the velocity vector at different points on the circular path. Since the direction of the tangent changes at every point,the velocity vector also changes,even though the magnitude of velocity (speed) remains constant.
