Forms and Conversion
ENERGYthe ability to do work
WORKis done when you
use a force to cause motion
WORKa force is moved
through a distance
“CLUES” – Types of Energy
• Kinetic Energy• Gravitational Potential Energy• Elastic Potential Energy• Chemical Energy• Thermal Energy• Electrical Energy• Nuclear Energy• Radiant Energy
Kinetic Energy
• Energy of motion• Examples:
KE = ½*M*V2
Gravitational Potential Energy• Stored energy that depends on an
object’s height• Examples:
GPE = M*g*H
Thermal Energy
• Energy of heat• Examples:
Chemical Potential Energy
• Stored energy in chemical bonds in compounds
• When released, energy can do work
• Examples:
Elastic Potential Energy
• Stored energy of a compressed or stretched object
• Examples:
Electrical Energy
• Energy associated with electrical charges
• Examples:
Nuclear Energy
• Energy stored within nucleus of an atom
• Examples:
Radiant Energy
• Energy that travels through space in waves
• Electromagnetic Spectrum• Examples:
Sound
• Form of kinetic energy• – movement of energy throughsubstances in the form of waves
