Escapement techniques used escapements, but these have only the name in common. The Chinese one worked intermittently; the European, in discrete but continuous beats. Both systems used gravity as the prime mover, but the action was very different. In the mechanical clock, the falling weight exerted a continuous and even force on the train, which the escapement alternately held back and released at a rhythm constrained by the controller. Ingeniously, the very force that turned the scape wheel then slowed it and pushed it part of the way back... In other words, a unidirectional force produced a self-reversing action—about one step
Mechanical energy simplified into since in circular motion, Newton's 2nd Law of motion can be taken to be Today, many technological devices convert mechanical energy into other forms of energy or vice versa. These devices can be placed in these categories: The classification of energy into different types often follows the boundaries of the fields of study in the natural sciences. Notes Citations Bibliography Mechanical energy In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The principle of conservation of mechanical energy states that
