Potential Energy and Work Conservative/Non
... • The total amount of energy in the Universe is conserved. This is a wonderful property of our Universe: Energy can be transformed from one type to another and transferred from one object to another, but the total amount is always the same. This is the principle of conservation of energy. No excepti ...

... 10) Read section 6.4 to the bottom of p. 131. You may recall from grade 9, 10, and 11 that energy is neither created nor destroyed. This is the Law of Conservation of Energy. It follows from this that if you do a certain amount of work to raise an object to a new height then the work you do to get ...
