Energy Basics
What type of energy does a moving baseball have?
Kinetic Energy
•The energy in moving objects
•The energy of motion or position
•Can be potential energy or kinetic energy
Mechanical Energy
What form of energy causes ice to melt?
Thermal Energy
What is the primary source of energy on Earth?
The Sun
Campfire
Chemical➡Thermal and Radiant
The stored energy of position. (two types...gravitational and elastic)
Potential Energy
Energy from the sun is transferred to the Earth by...
Electromagnetic Waves
What form of energy is produced by a musical instrument?
Sound Energy
•Wind – power generated by harnessing the energy from the movement of wind
•Solar – power produced by harnessing the energy from the Sun’s rays
•Geothermal – energy that comes from extreme heat within Earth
•Biomass – energy from recently living organisms such as leaves or plants - can be burned to release energy
•Hydropower – energy produced from the movement of flowing water
Renewable Energy
Nuclear Power Plant
Nuclear ➡ Thermal ➡ Mechanical ➡ Electrical
P.E. or K.E.
"At the Top"/ Compressed
Potential Energy
•The energy of heat
•Particles of hot objects move faster than the particles of cooler objects
Thermal Energy
What kind of wave can pass through the vacuum of empty space?
A. Conduction wave
B. Electromagnetic wave
C. Mechanical wave
D. Sound wave
B. Electromagnetic wave
RADIANT ENERGY
•Coal – fossil fuel; solid energy resource produced from plant remains
•Oil – fossil fuel; formed from the remains of small marine plants and animals buried under heat and pressure
•Natural Gas – fossil fuel; a flammable gas that occurs naturally underground
•Nuclear – energy produced by atomic reactions through nuclear fission (splitting the nucleus of an atom)
Nonrenewable Resource
A resource that is in limited supply.
Television
Electrical ➡ Radiant and Sound
What is the relationship between P.E. and K.E.?
They are an inverse relationship. When one goes up the other goes down and the opposite is true.
The energy locked in the nucleus of an atom
Fission- Splitting
Fusion- Combining
Nuclear Energy
Example
Sun (stars, Atomic Bomb, Power Plant)
The energy of moving electrons or electric charges
Electrical Energy
What are the pros and cons of renewable resources?
(Four pieces) This question you can earn 4X points; you only can loose 1X points.
Pro
1. They are replaced over time so they will not run out.
2. They produce very little waste products so they are clean for the environment.
Con
1. Renewable energy facilities can be expensive to start for the first time.
2. Renewable resources are not able to be used in all locations.

Using context clues...
"-ING" / Movment
Kinetic Energy
Energy stored in the bonds of molecules
A form of potential energy
Chemical Energy
(Food, Battery, Coal)
•The energy of light; also referred to as light energy or electromagnetic energy
•Travels in waves
•Travels in a straight path from one place to another
Radiant Energy
(TV, Traffic Light, Cell Phone)
What are the pros and cons of nonrenewable resources?
(Four pieces) This question you can earn 4X points; you only can loose 1X points.
Pro
1. They are able to be stored for use at a later time.
2. They are more cost-effective.
Con
1. They can be used up if they are not conserved.
2. They lead to the pollution of the environment.
