Physics in Rolling a Snowman



A few of my friends and I were making a snowman the other day and when I was rolling up the base, it reminded me of some physics. When you start, you clump together some snow which at first is a piece of cake. However, eventually as you keep rolling it and it gathers snow, the ball becomes bigger and heavier. It takes more energy and force to push it. As a result of this, your overall work increases. Finally, when you are ready to stack them to finish up your snowman, you lift the middle ball up and not only do you hear the sound waves produced by your back breaking but you attribute the fact that the snowman's different "layers" are not floating away due to gravity. Gravity is further exemplified when your snowman tips over.
