Law of conservation of energy states that: − Energy can neither be created nor be destroyed. Class-11-science » Physics. Answer. So, John Dalton, a British scientist put forward the hypothesis about atoms: a = Acceleration. Proof: − At point A. K. E = 0 m / s. P. E = m g h. P. E = m g h. At point B, K. E., 2 g h = V 2 − O 2. The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. All water molecules consist of hydrogen and oxygen atoms with a ratio of H: O = 2: 1 Further explanation The development of atomic theory starts from the first term conveyed by Greek scientists who suggested that every substance has the smallest particles so that the word atomos appears, which means it cannot be divided.
