1.	Can acceleration be produced without doing any work? Give example
Answer» Yes, centripetal force causes acceleration but no work is done by the force. A\xa0centripetal force\xa0is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Since the direction is always orthogonal(perpendicular) work done is zero.
