For Question, give a specific example of a system with the energy transformation shown. In these questions, W is the work done on the system, and are the kinetic, potential, and thermal energies of the system, respectively. Any energy not mentioned in the transformation is assumed to remain constant; if work is not mentioned, it is assumed to be zero. ? K ? ?W
ANSWER: In the above equation, kinetic energy converted to work. The simplest example will be, Imagine a high speed air flow in a particular direction. Whatever comes in it’s way it blows up that. The object which was at rest initially, by the force of wind got displaced in some direction. The dot product of the force of wind and the displacement of the object will give the work done by the wind. The wind has kinetic energy as it is moving, after it hits the object it will be converted to work. The work we got here is sometimes useful and sometimes not.
