Types of Energy & the Law of
Conservation of Energy
Types of energy
Kinetic Energy is energy
that is in motion. Moving
water and wind are good
examples of kinetic
energy.
Potential Energy is stored energy.
Examples of potential energy are oil
sitting in a barrel, or water in a lake in
the mountains
Mechanical Energy is the energy of
motion that does the work. An example
of mechanical energy is the wind as it
turns a windmill.
Electrical Energy is when electricity creates
motion, light or heat. An example of electrical
energy is the electric coils on your stove.
Many forms to obtain energy
Hydroelectric energy. This form uses the
gravitational potential of elevated water that was
lifted from the oceans by sunlight. It is not strictly
speaking renewable since all reservoirs eventually
fill up and require very expensive excavation
Solar. This form of energy relies on the nuclear
fusion power from the core of the Sun. This
energy can be collected and converted in a few
different ways.
Wind Power. The movement of the atmosphere is driven
by differences of temperature at the Earth's surface due
to varying temperatures of the Earth's surface when lit by
sunlight.
Law of Conservation of Energy
This law dictates that energy always
remains unchanged, but it can be
transformed in another type of
energy
It says that energy can not
be created or destroyed
It is a consequence of the dynamic
evolution of systems is governed by
the same characteristics in every
moment
