Energy
 Definition:
The ability to cause change or do work
 Teach
your neighbor the definition of Energy
Potential Energy
 Definition:
Stored energy. Energy due to position of an
object.
 Teach
your neighbor the definition of
Potential Energy using hand motions
Kinetic Energy
 Definition:
Energy due to motion
of an object.
 Teach
your neighbor the definition of Kinetic
Energy using hand motions
Chemical Energy – Form of PE
•
Is potential energy that is stored in chemical
bonds that hold molecules together.
•
Ex: Batteries, food, gasoline
Nuclear Energy – Form of PE
 Is stored in the
nucleus of an atom.
Mechanical Energy – Form of KE

Is the movement of objects and substances from
one place to another
Electrical Energy – Form of KE
 The
energy that an electric current carries
 Moving
electrons
Light Energy (Radiant Energy) – Form of
KE
•
Is radiant energy that travels in
waves (ROYGBIV)
•
In addition to visible light, ultraviolet
radiation, microwaves, x-rays and
infrared are all examples of this energy
Thermal Energy (Heat) – Form of KE
•
The energy given off by moving particles
•
The faster the particles are moving the
hotter it is
•
The slower the particles are moving the
cooler it is
Sound Energy – Form of KE
•
•
Sound Energy – The movement of energy
caused by vibration – A type of Mechanical
Energy
Examples – a string of a guitar vibrating
after you strum it, The reed of a wind
instrument vibrating when you blow air
through it, A balloon popping, A baby
crying.
Law of Conservation of Energy
 Energy
cannot be created nor destroyed it
can only be changed into other forms of
energy (transformations)
