Mechanical Energy We have always relied on mechanical
energy to do work. History is dotted with many discoveries
that have reduced effort required to do this work.
Wheels, pulleys, gears and levers have all been used to reduce effort
Watt
Chemical Energy The chemical reactions that occur in nature
all involve a change in energy level – giving off energy or requiring energy to occur
Photosynthesis and respiration in living things; chemical reactions in nature such as oxidation and electrolytic replacement
These chemical processes can be harnessed to generate other forms of energy such as electricity, heat and even light
