The energy possessed by a body by the virtue of its motion is termed mechanical energy or kinetic energy. Every moving object possesses mechanical energy. A body uses mechanical energy to try to work. Kinetic energy of a hammer is employed in driving a nail into a log of wood, mechanical energy of air is employed to run windmills, etc.

Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?
In each of the following a force, F is acting on an object of mass, m. The direction of displacement is from west to east shown by the longer arrow. Observe the diagrams carefully and state whether the work done by the force is negative, positive
