Demonstrating the center of mass. A wrench hurled through the air seems to be tumbling erratically, but the path made by the X on its handle, marking the center of Mass, tells the hidden truth. A ruler laid along the line of crosses in this stroboscopic picture shows that the center of mass moves in a straight line. The equal distances between the crosses indicate that it moves at a constant speed.
