Is it possible to have an accelerated motion with a constant speed? Explain

उत्तर
Yes, it is possible to have accelerated motion with a constant speed. For e.g. in a uniform circular motion, the body moves with constant linear speed with a constant centripetal acceleration acting towards the centre of the circle.
