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