1. USE THE EXAMPLE AT YOUR TABLE TO MAKE YOUR OWN ENERGY BOOK. FILL IN ALL OF THE INFORMATION ON THE APPROPRIATE PAGE. USE YOUR RUBRIC SO THAT YOU CAN ACHIEVE A HIGH GRADE ON YOUR BOOK. ENERGY BOOK

2. HEAT ENERGY Heat energy is the energy associated with the motion of particles in a substance. When there is a lot of heat energy, the particles move fast and there is high temperature When there is little heat energy, the particles move slower and there is low temperature HEAT LAW: DURING A TRANSFER, HEAT ALWAYS MOVE FROM WARMER OBJECT TO COLDER OBJECT SOURCES OF HEAT ENERGY: Sun, burning material, electricity

3. SOLAR ENERGY Energy from the Sun Provides heat and light energy for Earth Plants use solar energy for photosynthesis to make a sugar (their food) Provides almost all of the energy that we use on Earth Source of solar energy -- Sun

4. CHEMICAL ENERGY Energy that is stored in particles of matter Chemical energy can released when these particles react to form new substances Source of chemical energy: Sun

5. ELECTRICAL ENERGY Energy flowing in an electric circuit SOURCES: Batteries, solar energy in solar cells, fuels, hydroelectric energy in generators

6. 2 TYPES OF MECHANICAL ENERGY Mechanical Potential – stored energy due to position of object Stretched rubber band & height of object are examples Water behind a dam has stored potential energy Mechanical Kinetic – energy of motion Faster an object, more kinetic energy Slower the object, less kinetic energy
