Physics
Give an example of motion of a body moving with a constant speed, but with a variable velocity. Draw a diagram to represent such a motion.
Answer
The motion of a body in circular path, is an example of a body moving with a constant speed and variable velocity because the direction of motion of body changes continuously with time.
At any instant, the velocity is along the tangent to the circular path at that point.
The figure above shows the direction of velocity v at different points A, B, C and D of the circular path.
