Escapement eventually became the escapement of choice for turret clocks, because their wheel trains are subjected to large variations in drive force caused by the large exterior hands, with their varying wind, snow, and ice loads. Since in a gravity escapement the drive force from the wheel train does not itself impel the pendulum but merely resets the weights that provide the impulse, the escapement is not affected by variations in drive force. The 'Double Three-legged Gravity Escapement' shown here is a form of escapement first devised by a barrister named Bloxam and later improved by Lord Grimthorpe. It is the
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
