Vector addition and subtraction applet - helps you quickly check vector arithmetic by visually constructing the vectors A and B, their magnitudes, angles, components, and computing A +B, A -B, B - A, and A dot B, which we'll discuss later.
Unfortunately sometimes the labels on the purple buttons (left side of applet) don't work. They are, from top to bottom, A +B, A -B, and B - A, respectively. You have to "Clear last" after clicking one of these buttons before the next button will work.

10/13 C13: Oscillations - whenever a stable equilib,
U=½kx2 has F = -dU/dx = kx has an equilibrium at x=0 and d2U/dx2 = k > 0, so this is concave up and thus a stable equilibrium, hence masses oscillate on a spring.
