• The greater the mass of an object, the more inertia must be overcome to move or stop it.
• As the resistance to be overcome increases, parts of the body are repositioned so that force can be applied more advantageously.18
• The basic precepts of Newtonian physics underscore the importance of choosing the right combination of levers, applying them in the correct manner, and favoring curvilinear over angular gestures.
• keeping the amplitude of these curved movements as small as possible,…
• Moving in toward the center of the body tends to require less effort…
