1. The law of conservation of energy states that energy is neither created nor destroyed. What does this mean? 2. Why is the conservation of energy so important? Please Help!!!

1. 1. It means that you can't actually create energy, merely convert energy from one form to another. 2. Well the fact that you can't create or destroy energy does have a lot of important consequences in how our technology works along with how the world works.
2. if you realize that every thing in this world is in a circle of life and death and the same rule works also for energy
3. Matter is neither created or destroyed... e=mc/2 Conservation of energy relates to efficiency. The ultimate goal as it relates to conservation of energy is perpetual motion... which is hard a achieve do to friction. The waste product of less than 100% efficiency is heat.
