WebA moment and an instant are both the same: just points on the time axis for a physicist. The Wikipedia page apparently has a different definition. What's the physics question here? – ACuriousMind ♦ Mar 13, 2016 at 14:25 3 moment (of time) and instant and not precisely defined terms in physics. WebThe direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. This …
Webrelaxation phenomenon, in physics and chemistry, an effect related to the delay between the application of an external stress to a system—that is, to an aggregation of matter—and its response. It may occur in nuclear, atomic, and molecular systems. Chemists and physicists use relaxation effects to study processes that take only a fraction of a second. When an …
WebA Slightly Changing Constant. One of the confusing things for nonscientists about Planck's constant is that the value assigned to it has changed by tiny amounts over time.
