6.P.3A.1 Types of Energy
Transcript of 6.P.3A.1 Types of Energy
● Gravitational potential energy is
of an object is greater because
kinetic energy was required to raise the object to the
● Gravitational potential energy is greater when the mass of the object is greater because more kinetic energy is required to lift the
Gravitational Potential Enegy
■ Potential energy is
■ Mechanical potential energy is related to the
of an object.
■ A stretched rubber band has potential energy. This is called
energy is the energy due to the motion (
) and position (
) of an object.
When objects are set in motion or are in a position where they can be set in
, they have mechanical energy.
energy is energy stored within the chemical bonds in matter.
● Chemical energy can be

● Thermal energy is associated with the
of the particles in a substance.
● All matter is made up of
(particles) that move
when they heat up.
The faster the particles move, the

on a shelf has potential energy. Since
can pull the book to the floor, this is called
potential energy. The
of an object affect gravitation potential energy.
Mechanical Potential Energy Continued...
● Examples of this can include, but are not limited to, lifting a book to a height of
meters instead of
meter; and lifting a
to a height of one meter and then lifting a
ball to a height of 1 meter.
