... 3. Explanation: A hanging block of wood attached to a string has potential energy. When released, the block falls, turning a shaft with attached blades. As the blades rotate with mechanical energy, the mechanical energy is transformed into heat, thus heating up the water. 4. a) 441 N b) Mass is scal ...

... Any of the above forms of energy can be changed into other forms of energy. However, no energy is ever lost, nor can it be created from nothing. This can be stated as a law so that it can be applied to new situations as they are encountered: Energy is never created or lost, it can only be converted ...

... 2nd Law: "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy. Example: A watchspring-driven watch will run until the potential energy in the spring ...
