Law of Conservation of Energy
•Energy can be transformed
from one form into another or
transferred from one region to
another, but energy cannot be
created or destroyed.
What is energy?
•Energy is the ability to cause
change.
•There are 2 main types of energy:
Potential & Kinetic
Potential Energy is energy that is
stored in an object but is not
being used.
An object that is not moving has
potential energy.
Forms of Potential Energy
•Gravitational Potential Energy –
energy stored between the object
and the earth
•Depends on the object’s weight and
height
• Elastic Potential Energy – stored in
objects that are compressed or
stretched.
• Chemical Potential Energy – stored
in the chemical bonds between
atoms.
Kinetic energy is the energy of
motion.
An object that is in motion has
kinetic energy.
What effects the Kinetic Energy?
• Speed
Faster speed = More Kinetic Energy
•Mass
Greater mass = More Kinetic Energy

one form to another.
