2 main types of energy
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
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.

  • Thermal
m echanical 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

r adiant energy
Radiant Energy
  • Energy carried by electromagnetic waves. Light and Solar energy.
  • Examples: Light, microwaves, X-rays, Sun, radio, satellite

Kinetic

Energy

s ound energy
Sound Energy
  • Caused by the vibration of particles in the air.
  • Examples include the following:

Guitar, piano

c hemical energy
Chemical Energy
  • Energy stored in matter because of its chemical makeup
  • Examples: Food, wood, fossil fuels (gas, coal, oil), battery, decay,photosynthesis

Potential

Energy

e lectrical energy
Electrical Energy
  • Energy produced by electric charges
  • Examples: electricity, lightning

Kinetic

Energy

n uclear energy
Nuclear Energy
  • Energy stored in the nucleus of an atom
  • Examples: splitting of an atom, fusion from Sun

Potential

Energy

t hermal heat 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.
