Types of Energy
1.Chemical
potential or kinetic
in atoms
electrons (-) negative charge
protons (+) positive charge
neutrons no charge
charges create chemical energy

in our bodiescontained in atoms -proteins and
chemicalsfood converted into energy -metabolismexhale heat energy
measured in calories (kilocalories)
Kcal = the amount of heat required to raise 1 kilogram of water 10 C
we burn this as energy

2. Heat Energy –thermal potential and kinetic burning coal or oil steam turns a turbine energy that is produced or is a result of a
chemical reaction

3. Radiant energy
potential or kinetic
SUN -through chemical reactions on the
sun
transferred to the earth through the atmosphere
radio waves, visible light, ultraviolet light

4. Mechanical energy
potential or kinetic
machines
makes work easier for us -mechanical
advantage
5. Electrical energy -wire
potential or kinetic energy

electrons move
uses a magnetic field
turns motors, powers all of our electrical equipment
activates electrical activity in storms
-lightning, static, electrical

Energy in a System
• A system is a set of objects working together to accomplish a job
• The amount of energy within a system remains constant. It only changes forms
• Example a person creating heat with sticks

System
The person contains chemical energy.
Let's say 50 Joules of chemical energy
Friction uses up 20 Joules of the beginning energy
Th heat is given off equals 30 Joules of energy
30 + 20 = 50 the total amount of energy remains constant and only changed forms
