Examples of how mechanical energy is used
WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. WebSep 12, 2024 · We can illustrate some of the simplest features of this energy-based approach by considering a particle in one-dimensional motion, with potential energy U (x) and no non-conservative interactions present. Equation 8.4.1 and the definition of velocity require. K = 1 2mv2 = E − U(x) v = dx dt = √2(E − U(x)) m.
