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. W ?? ?K
ANSWER: W K Here the work done got converted to kinetic energy directly. And as the other things are absent in the equation so they are considered to be constant. The example for this is, Suppose you apply some force on a block which is at a frictionless surface. By the force the block will start to move and the force times displacement will provide the information about the work done. This work done on the block will be converted to the kinetic energy of the system as the block which was initially at rest had a velocity now. And we know that the kinetic energy is some constant times the velocity square.
