- What is
energy?
- Is the capacity of a system to
do work
- Types of energy
- There are 23 types of energy in
total.
- +Electric energy, luminous energy, mechanical energy, heat energy, wind energy,
solar energy, nuclear energy, kinetic energy, potential energy, chemical energy,
hydraulic power, sound energy, radiant energy, photovoltaic power, energy of
reaction ionic energy, geothermal energy, wave power, electromagnetic energy, and
some other
- The 7 more importants are
- Electrical energy
- Is the energy created by electrons.
All matter contains atoms that
contain electrons. When electrons
are force down a conductive path;
the movement produces
electricity.
- Luminous energy
- The radiant energy of electromagnetic waves in
the visible portion of the electromagnetic
spectrum.
- Mechanical energy
- Is the energy that is possessed by an object
due to its motion or due to its position.
- Solar energy
- Solar energy is the technology
used to harness the sun's energy
and make it useable.
- Nuclear energy
- Is energy in the core (nucleus) of
an atom. Is the enormous
energy in the bonds that hold
atoms together. It can be
released from atoms into two
ways: nuclear fusion and nuclear
fission
- Wind energy
- Is the use of air flow through wind
turbines to mechanically power
generators for electricity.
- Thermal energy
- Is what we call energy that comes from the
temperature of matter. The hotter the
substance, the more its molecules vibrate, and
therefore the higher its thermal energy.
