Transcript of Types of Energy Chapter 9. What is Energy? Energy is the ability to do work.
What is Energy?
When one object does work on another, energy is transferred from the first object to the second object.
Electromagnetic
• Caused by moving electrons (negative particles)
• Includes the EM spectrum• Ex. electricity, magnets,
light, x-ray, etc.
Nuclear
Found within the nucleus of an atom
Extremely strong Used to create nuclear
power or nuclear weapons.
Law of Conservation of Energy
• States “Energy can not be created nor destroyed.”
• Energy simply changes types (forms)
Law of Conservation of Energy
• In a system the energy in must equal the energy out
• Energy In = Energy Out
Law of Conservation of Energy
Energy In = Energy Out• EM • Thermal (heat)
• Mechanical (moving air & sound)
Law of Conservation of Energy
Energy In = Energy Out• Chemical
(wood)• Thermal (heat)
• EM (light)
•Mechanical (sound)
Law of Conservation of Energy
Energy In = Energy Out• Chemical (gasoline & battery)
• Mechanical (motion)
•Thermal (heat from friction)
Law of Conservation of Energy
Energy In = Energy Out• Chemical
(food)• Mechanical (movement)
• Thermal
