The Art of War (孫子兵法), Energy 埶篇

故善戰人之埶如轉圓石於千仞之山者埶也

Thus the energy developed by good fighting men is as the momentum of a round stone rolled down a mountain thousands of feet in height. So much on the subject of energy.

Lionel Giles's notes

The T‘ung Tien omits 善. The chief lesson of this chapter, in Tu Mu’s opinion, is the paramount importance in war of rapid evolutions and sudden rushes. “Great results,” he adds, “can thus be achieved with small forces.”
