WebSep 1, 2024 · 1. Static Friction Definition: It is an opposing force which comes into play when one body tends to move over the surface of the other body but actual motion is not taking place. Static friction is a self-adjusting force which increases as the applied force is increased. Static friction opposes impending motion. 2. WebAug 30, 2005 · 43,017. 973. "Energy" is a book-keeping device. It was noted pretty early on in physics that in simple collisions, two quantities mass*velocity and 1/2 * mass* velocity 2 stayed the same which made them easy to use- one was called "momentum" and the other "kinetic energy". It was observed that the speed of an object (and so it's kinetic energy ...
