^{[e]} - Heat [r]: A form of energy that flows spontaneously from hotter to colder bodies that are in thermal contact.
^{[e]} - Momentum [r]: mass of a particle times its velocity (a vector).
^{[e]}- Angular momentum (classical) [r]: The tendency of a rotating object to resist changes to its rotational motion.
^{[e]} - Conservation of momentum [r]: A fundamental law of nature, that states that the total momentum of a closed system of objects (which has no interactions with external agents) is constant.
