SES194 Energy in Everyday Life Unit 1 Conservation The word “conservation” is generally understood to mean to prevent wasteful use of a resource, to save, to protect. If we are speaking casually, we could use one of these meanings and each would know what the other one meant. -Conservation has a different meaning when used in a technical sense - the total value of a quantity is a constant. -There is a fact, a law governing all natural phenomena that are known to date.There is no known exception to the law - it is exact as far as we know.This law is called the conservation of energy. -It states that there is a certain quantity, which we call energy, that does not change within the manifold changes which nature undergoes. -It says there is a numerical quantity which does not change when something happens. Sarah Booth -It is not a description of a mechanism or anything concrete, it is just a strange fact that we can calculate the number again, it is the same. -Energy is conserved; it cannot be created or destroyed. Objects that have now from changes of energy (work done) with other objects. Sarah Booth
