1. Energy Def. 2 categories Kinetic
Energy Potential Energy Waves
ability to do work or cause change Kinetic and
Potential KE is motionof waves, electrons,
atoms, molecules, substances, and objects PE
is stored energy and the energy of
positiongravitational energy longitudinal vs.
transversal waves Longitudinal Transversal

2. Types of KE Electrical Energy Radiant
Energy
movement of electrical charges applying a force
can make some of the electrons move Ex.
electrical charges moving through a
wire lightning electromagnetic energy that
travels in transverse waves radiant energy
includes visible light, x-rays, gamma rays and
radio waves, microwaves, UV rays Ex. light
solar energy

2. Types of KE (cont) Thermal
Energy Motion Energy Sound
heat, internal energy in substancesvibration
and movement of atoms and molecules within
substances Ex. geothermal energy movement of
objects and substances from one place to
another Ex. Wind movement of energy through
substances in longitudinal waves Sound produced
when a force causes an object or substance to
vibrate energy transferred through substance in
a wave.

3. Types of PE Chemical Energy Stored
Mechanical Energy Gravitational Energy
energy stored in bonds of atoms and molecules,
energy that holds these particles together Ex.
food, petroleum, natural gas, and
propane energy stored in objects by application
of force Ex. compressed springs stretched
rubber bands energy of position or place. Ex. A
rock resting at the top of a hill Hydropower,
such as water in a reservoir behind a dam

3. Types of PE (cont) Nuclear Energy
energy stored in nucleus of an atomenergy
that holds nucleus together, energy can be
released when the nuclei are combined or split
apart nuclear power plants split nuclei of
uranium atomsfission The sun combines the
nuclei of hydrogen atomsfusion scientists
working on creating fusion energy on earth, ie
cold fusion
