参考答案: Your gravitational PE will change according to $\Delta PE=mg\Delta y.$ If we choose some typical values of $m=80$ kg and $\Delta y=0.75$ m , then $\Delta PE=\begin{pmatrix}80&\mathrm{kg}\end{pmatrix}\begin{pmatrix}{9.8}&\mathrm{m/s^{2}}\end{pmatrix}\begin{pmatrix}{0.75}&\mathrm{m}\end{pmatrix}=590$ J
