They must be able to recognize if an equation is balanced or unbalanced before they can learn to complete the process of balancing for themselves. Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant. Use this study guide to help you understand the law itself as well as the law of conservation of energy formula. Hang masses from springs and adjust the spring constant and damping. Understand the role of the mass in a conservation of energy situation. Get an answer for 'How is the law of conservation of energy applied to the processes of photosynthesis and cell respiration?' and find homework help for other Science questions at eNotes Conservation of Mass Worksheet Key Background Antoine Lavoisier was a French chemist who did most of his work between 1772-1786. The law of momentum conservation can be stated as follows. To solve problems with work and energy one needs to identify a system that one is working with. It would appear that vaulters have discovered a way to "violate" the law of conservation of energy.
