V111. Video Demonstration: Center of Mass

	The Canada goose to the left is able to stand comfortably on one leg. By angling the leg to the side, the center-of-mass of the goose remains vertically above the webbed foot, which provides a wide base. (The photo was taken in Duke Gardens.)
	Under normal circumstances, a person couldn't stand as shown to the right, because the body's center of mass is not vertically above the base of the feet. In this case, though, a strong wind to the right helps this brave soul maintain balance. (The photo was taken on Falls Lake during tropical storm Isabel.)

Read section 9.7 of your text. Then watch the following two clips on center-of-mass and then do the corresponding assessment.
