- Slide 3
- What is energy? Energy is the ability to do work.
- Slide 4
- Law of Conservation of Energy Energy cannot be created or destroyed.
- Slide 5
- There are two states of energy or types of energy. Potential and kinetic.
- Slide 6
- Potential Potential is stored energy
- Slide 7
- Kinetic Kinetic is the energy of motion.
- Slide 8
- There are five main forms of energy. Chemical Mechanical Electromagnetic Heat (thermal) Nuclear
- Slide 9
- Chemical Energy Energy that is available for release from chemical reactions.
- Slide 10
- Mechanical Energy Energy due to a objects motion (kinetic) or position (potential).
- Slide 11
- Electromagnetic oLight energy o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands oMoving electric charges
- Slide 12
- Heat or Thermal Internal motion of atoms. The heat energy of an object determines how active its atoms are.
- Slide 13
- Nuclear Nuclear energy is the energy stored in the nucleus of an atom and can be broken into: fusion (energy of the sun which is the combing of two or more nuclei) and fission(the splitting of an atom like in a nuclear reactor).
- Slide 14
- Energy Transfer Chemical Electrical Sound (mechanical) Light (Electromagnetic) Thermal Mechanical
- Slide 15
- There are three types of (energy) heat transfer. Convection Conduction Radiation
- Slide 16
- Convection Convection is the transfer of heat energy in a gas or liquid by movement of currents due to changes in density.
- Slide 17
- Conduction is the transfer of energy through matter from particle to particle.
- Slide 18
- Radiation Allows heat to be transferred through wave energy.
- Slide 19
- Slide 20
- Renewable Renewable resources are those resources that can be replaced as they are used up. Some examples include: soil air water wood sunlight
- Slide 21
- Non-Renewable Nonrenewable resource are those natural resources that cannot be replaced once they are used up. Some examples include: oil coal gas uranium
