ENERGY
Energy can be broken up into
6 types
Mechanical Energy
Energy an object has because of its motion or position
Thermal (or Heat) Energy
Energy a substance has based on the movement of its
particles
Electromagnetic Energy
Energy carried by electromagnetic waves (light, x-rays,
radio waves, etc.)
Electrical Energy
Energy produced by the flow of electric charges
Chemical Energy
Energy stored in chemical bonds
Nuclear Energy
Energy contained within the nucleus of an atom
These types can be broken into
2 Forms
Potential Energy: Stored energy
an object could potentially have
Kinetic Energy: Energy an object
has because it is moving
Law of Conservation of Energy
• Energy cannot be created nor destroyed, but
only transferred from one type or system to
another
Taking a closer look at some of
those types of energy…
Thermal (or Heat) Energy
• Temperature: a measure of how fast the
particles are moving in a substance
– What is temperature measured in?
• Heat: the transfer of thermal energy
between substances at different temperatures
Energy Transfer
• Temperature naturally wants to equalize
• Heat will flow from warmer to cooler
objects until temperatures are equal
Hot  Cold
