Different types of energy 6:01
Two Energy Forms
• Potential
– Potential energy stored and the
energy of position.
– Potential means capable of being
or becoming or possible.
• Kinetic
– Kinetic energy is motion, the
motion of waves, electrons,
atoms, molecules and
substances.
– Kinetic means
• adjective 1.pertaining to
motion.2.caused by
motion.3.characterized by
movement: Running and dancing
are kinetic activities.
Types of Potential Energy
• Chemical
• Nuclear
• Stored Mechanical
• Gravitational
Chemical Energy
is Potential Energy
• Chemical Energy: Stored in the bonds of
atoms and molecules.
Examples:
–Biomass

Propane
Coal
Nuclear Energy
is Potential Energy
• Nuclear energy is the energy stored in the
nucleus of an atom – the energy that holds
the nucleus together.
• Examples are
• Uranium Atom
• Fusion – The Sun
is a process in which two
nuclei join, forming a
larger nucleus and
releasing energy.
• Nuclear Fission –
splitting the atom
Stored Mechanical Energy
is Potential Energy
• Stored Mechanical
Energy is energy
stored in objects by
the application of a
force.
• Examples are springs
and Rubber bands
Gravitational Energy
is Potential Energy
• Gravitational
Energy is the
energy of Place
or position.
• Examples are
Water behind a
Dam, when
released it
becomes
energy of
motion.
Types of Kinetic Energy (Motion)
• Radiant
• Thermal
• Motion
• Sound
• Electrical Energy
Radiant Energy
is Kinetic Energy
• Electromagnetic energy that travels in
transverse waves. Solar energy, x-rays &
gamma rays are examples.
Thermal Energy
is Kinetic Energy
• Thermal energy or
heat is the internal
energy in substances
– the vibration and
movement of atoms
and molecules within
substances.
• Geysers are an
example.
One Benefit of Geothermal Energy
Motion
is Kinetic Energy
• The movement of objects or substances from
one place to another. Wind and hydropower are
two examples.
Sound
is Kinetic Energy
• Sound is the movement of energy through
substances in longitudinal waves.
Electrical Energy
is Kinetic Energy
• Electrical energy is
the movement of
electrons. Lightning
and electricity.
