Tug of war is a game played by most people in their youth. In the wild, animals tussle with each other in similar ways but with much more at stake â€" e.g., a crocodile grabbing a zebra by its head to drag it into the Nile. Winning this game is much harder than not losing it (i.e., settling for a stalemate). Why? Design an experiment that tests this hypothesis, and then explain your predictions in terms of force generation and energetics. Make sure to choose your species carefully, and provide sufficient detailed information to show your understanding of how data are collected, analysed and interpreted.
