Mrs. Wharton’s Science Class
 The
energy possessed by an object due to its
motion or its stored energy of position.
 Mechanical
energy can be either potential
energy or kinetic energy.
 An
object that possesses mechanical energy
is able to do work.
 Mechanical
energy is the form involved in the
operation of simple machines.
 Objects
with potential energy do not use
their energy until they move.
 Any
object that can move to a lower place
has potential to do work on the way down.
 Energy
 Can
of motion.
vary at different points in a roller
coaster.
 Can
appear in different forms such as motion
or heat.
 Energy
can travel in different forms, such as
sound, light or electricity.
 The
workings of the universe plus all of
present day technology can be viewed from
the perspective of energy flowing from one
place to another and changing back and forth
from one form to another.
 The
total energy of the particles in an object
 When energy increases the particles move
faster
 When energy decreases the particles move
slower
 Chemical
energy is potential energy stored in
chemical bonds that hold chemical
compounds together.
 They are found in foods you eat and matches
before they are lit.
 Chemical energy is even found in the cells of
your body.
 Electrical
energy is moving electric charges
that produce electricity or electrical energy.
 This is found in batteries, or power lines
used to run such devices as computers ,
radios or lights.
 The
light that you see each day is a form of
electromagnetic energy.
 This form of energy travels in waves.
A
type of potential energy that is stored in
the core or nucleus of an atom.
 Nuclear power plants are used to produce
types of electricity. (Simpsons)
