Energy Transformations

2 Main Types of Energy Kinetic Energy: the energy of motion (faster-more) Potential Energy: stored energy (based on position, higher-more)

The Law of Conservation of Energy Energy cannot be created Energy cannot be destroyed It can be transferred from one form to another. Thus, when the water at the top of the waterfall plunges over the edge, potential energy is converted to kinetic energy.

Energy Transformations As plates push against each other stress builds (potential energy). When the plates move or break the energy is released as kinetics energy.

Major types of energy… Chemical Radiant Thermal Nuclear Mechanical Electrical

Chemical Energy Energy stored in matter because of its chemical makeup Examples: Food, wood, fossil fuels (gas, coal, oil), battery Potential Energy

Radiant Energy Energy carried by electromagnetic waves Examples: Light, microwaves, X-rays, Sun, radio, satellite Kinetic Energy

Thermal (Heat) Energy Energy related to the temperature of a substance Examples: moving particles substances – the higher the temperature the faster the particles move. Kinetic Energy

Nuclear Energy Energy stored in the nucleus of an atom Examples: splitting of an atom Potential Energy

Mechanical Energy Sum of total energy of matter because of its motion or position Examples: wind, moving water, falling rocks, stretched spring, machines Kinetic Energy

Electrical Energy Energy produced by electric charges Examples: electricity, lightning Kinetic Energy
