The capacity to do work is called energy.

Energy can be classified as mechanical energy, electrical energy, heat energy and sound energy etc.

Mechanical energy is further classified into two types- Potential Energy and Kinetic energy.

The energy possessed by a stationery object is potential energy.

The energy possessed by a moving body is kinetic energy.

The statement "A boat sails across the ocean." thus gives an example of a body which has kinetic energy because the boat is moving on the ocean.
