Concept introduction: The work is performed on an object when an object moves a certain distance s due to the force F. Mathematically, it is indicated by the dot product of the force vector F and the distance vector s. The mathematical equation is given below, Work = F .s = | F | | s | cos θ Where θ is the angle between the vectors F and s. The unit of work is joules. Work is a way to transfer the energy. The energy is defined as the ability to do work and so energy and work are described using the same unit in joules. Internal energy is the total energy of the system. For an isolated system the total energy of the system remains constant. Moreover the total energy of a system changes the energy change goes into either work, heat.Start your trial now!
