 Mechanical
 Electrical
 chemical
 sound
 thermal
 radiant
 It
takes on two forms
• Kinetic
• Potential
 The
energy of an object in motion
 Speed
(or velocity) at which the object is
moving
 The mass of the object
 Heavier
objects will have more kinetic
energy than lighter objects
 Described
as stored energy
• energy is stored by doing work against a force
like gravity
• Also, the amount of potential energy can
increase with mass
 Remember
that energy cannot be
created nor destroyed
 It will just change to other forms
 Remember
that the Sun is the source of
almost all energy on the Earth
