WebSep 12, 2024 · The total mechanical energy of the wave is the sum of its kinetic energy and potential energy. The kinetic energy K = 1 2 mv 2 of each mass element of the string of length Δ x is Δ K = 1 2 ( Δ m)v y2, as the mass element oscillates perpendicular to the direction of the motion of the wave. WebSolution. Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string.

WebWhen work is done energy is transferred to the object and it gains gravitational potential energy. If the object falls from that height, the same amount of work would have to be … In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes. In all real systems…
