What is energy?
What is energy?
Energy is the ability to do
work or cause change
There are two basic kinds of
energy: kinetic energy and
potential energy.
Kinetic energy - energy that
an object has due to its
motion
The kinetic energy of an object depends on
both its mass and velocity.
Greater MASS = Greater Kinetic Energy
Greater VELOCITY = Greater Kinetic Energy
25 mph
60 mph

Potential energy - stored
energy that results from the
position or shape of an
object
This type of energy has the
potential to do work.
Potential Energy
Types of Potential Energy:
• Gravitational Potential
Energy
• Elastic Potential Energy
Potential energy related to
an object’s height is called
gravitational potential
energy.
Potential energy associated
with objects that can be
stretched or compressed is
called elastic potential
energy.

Section 2
Forms of Energy
Mechanical Energy - form of
energy associated with the
position and motion of an
object
Mechanical Energy = Potential Energy + Kinetic Energy
Thermal Energy – total
potential and kinetic energy
of the particles in an object
Electrical Energy – energy
of electric charges
Chemical Energy – potential
energy stored in the chemical
bonds that hold chemical
compound together
Nuclear Energy – potential
energy stored in the nucleus of
an atom
Electromagnetic Energy –
energy of light and other forms
of radiation

Energy
Transformations
and Conservation
Most forms of energy can be
transformed into other forms.
Energy Transformation – a
change from one form of
energy to another
The Law of Conservation of
Energy - states that energy
cannot be created or destroyed
So where does the energy go?
Ex: A speeding car slams on
the breaks.
Ex: A glass falls off the counter
and breaks.
