Grasshopper escapement Grasshopper escapement The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands forward at a steady rate. The grasshopper escapement was used in a few regulator clocks built during Harrison's time, and a few others over the years, but has never seen wide use. The term "grasshopper" in this connection, apparently from 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
