FIG. 21.6 A modeled pendulum in Algodoo with dynamic vector arrows as they change throughout the pendulum swing—velocity in black, external forces on the bob in white, and the sum of all external forces in green (left). A constructed “car” in Algodoo with motors on the front and rear wheels ascends a slope (right). Dynamic vector arrows are displayed for the orange box, while the graph above shows the time dependence of the box's gravitational potential energy.

... importantly, heat. Réne Descartes had already postulated the conservation of motion—that is, that a body that moves will continue to move in a straight line—with the product of the “mass” and the “velocity” of a body being a conserved quantity. 2 Christian Huygens proposed that in the case where the center...
