Escapement a statue of an angel to follow the sun, the consensus is that this was not an escapement. The first mechanical escapement, the verge escapement, was used in a bell ringing apparatus called an "alarum" for several centuries before it was adapted to clocks. In 14th-century Europe it appeared as the timekeeper in the first mechanical clocks, which were large tower clocks. Its origin and first use is unknown because it is difficult to distinguish which of these early tower clocks were mechanical, and which were water clocks. However, indirect evidence, such as a sudden increase in cost and construction
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
