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… WebMar 29, 2024 · Mechanical Energy (M.E.) = Kinetic Energy (K.E.) + Potential Energy (P.E.) Where, Kinetic Energy (K.E.) = (1/2)mv 2 Potential Energy (P.E.) = m × g × h ∴ Mechanical Energy (M.E.) = ( (1/2)mv2) + (m × g × h) Where, m = mass of object, v = velocity of object, g = acceleration due to gravity, h = height of object from ground.
