# A boy is whirling a stone tied with a string in an horizontal circular path. If the string breaks, the stone (a) will continue to move in the circular path (b) will move along a straight line towards the centre of the circular path (c) will move along a straight line tangential to the circular path (d) will move along a straight line perpendicular to the circular path away from the boy

Answer: (c) will move along a straight line tangential to the circular path

At any instance of time objects in circular motion tend to be in rectilinear motion. The object keeps on moving due to centripetal force and it moves along a straight line tangential to the circular path when strings break.

## Circular motion

Circular motion is described as a movement of an object while rotating along a circular path. Circular motion can be either uniform or non-uniform. During uniform circular motion the angular rate of rotation and speed will be constant while during non-uniform motion the rate of rotation keeps changing.
