Feb 13, 2013· It's having a balance over time that will help you stay at a healthy weight for the long term. Children need to balance their energy, too, but they're also growing and that should be considered as well. Energy balance in children happens when the amount of ENERGY IN and ENERGY OUT supports natural growth without promoting excess weight gain.
Mass and Energy Balances. One of the fundamental laws of physics states that mass can neither be produced nor destroyed---that is, mass is conserved. Equally fundamental is the law of conservation of energy. Although energy can change in form, it can not be created or destroyed. These two laws of physics provide the basis for two tools which ...
