It is possible to exert a force which does work on a body without clinging its kinetic energy? If so, give example.

Solution
Yes. If the force exerted on the body does no result in a sustained movement, you may say
that the force has done a work but not changed kinetic energy. Examples: 1. Compressing on expanding a spring 2. Moving an object from a place to another place by applying some force. Needless to mention, if a force acting on a body changes velocity of the object, it changes it's kinetic energy.
