Give a specific example of a system with the energy transformation shown. In these questions, \(W\) is the work done on the system, and \(K, U\), and \(E_{\mathrm{th}}\) 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.

\(W \rightarrow U\)
