An object initially at an elevation of 5 m relative to Earth’s surface with a velocity  of 50 m/s is acted on by an applied force R and moves along a path. Its final  elevation is 20 m and its velocity is 100 m/s. The acceleration of gravity is 9.81  m/s2 . Determine the work done on the object by the applied force, in kJ.

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
