Why Energy is conserved
The main idea of this page is to elaborate a little more on why energy is conserved and to understand it is a more simplified way. The thought about the fact that energy is neither created nor destroyed can be a mind boggling one simply because energy always seems to be coming from somewhere, so where does it go? The main idea behind why energy is conserved and neither created or destroyed is that it is just transferred to other forms. The first law of Thermodynamics states that the amount of energy in the universe is a constant, fixed amount. Is doesn’t go away and it doesn’t appear randomly.
A Mathematical Model
The mathematical equations that are used to model this topic include many different equations, but they all relate back to the energy principle, ΔEsystem = WSurr +Q. W is the work cone by the surroundings and Q is the thermal energy. The change in energy will be always zero because energy is transferring to other forms of energy within the system or surroundings. Other Important equations include: K = ½mv2, ΔUg = mgΔh, E = K + U, Ei = Ef, Ki + Ui = Kf + Uf, W = F̅Δs cos θ.
