... Newton’s third law of motion, the wall exerts a force Fwall on feet on her, equal in magnitude but in the direction opposite to the one she exerts on it. The line around the swimmer indicates the system of interest. Note that Ffeet on wall does not act on this system (the swimmer) and, thus, does no ...

... • You may not know it, but every atom/molecule in your body is oscillating. • For any system, there's at least one state that the system is of the lowest potential energy. This is a point of stable equilibrium, or the bottom of the valley in a potential vs. position curve. • If the system is of a sm ...
