7 Forms of Energy
What are the 7 forms of Energy?
Chemical Energy Electromagnetic (light) Energy Mechanical Energy Nuclear Energy Sound Energy Thermal (Heat) Energy Electrical Energy
(Burning wood in a campfire) is an example of what forms of energy transforming?
Chemical → Thermal (heat)
(Toaster making toast) is an example of what forms of energy transforming?
Electrical → Thermal (heat)
(Sun shining on a solar panel) is an example of what forms of energy transforming?
Electromagnetic (light) → Electrical
What happens when energy changes into a different form?
Energy is conserved
Ultraviolet waves, sunlight, and infrared radiation are all examples of which type of energy?
Examples of Light (Electromagnetic) Energy
Which type of energy is produced by the vibrations of particles in solids, liquids, and gases?
Sound Energy
What is Thermal (heat) energy?
The result of movement (kinetic energy) of particles in matter.
What is Mechanical energy?
energy in motion is mechanical energy (moving car, stretched elastic or flattened coil)
What is Sound energy?
energy produced by the vibration of particles that people and animals can detect
What is Chemical Energy?
energy stored in bonds between atoms, released in reactions
What is Nuclear energy?
energy that holds atoms together is released when they are split apart
What is Electromagnetic (light) energy?
energy that moves in waves (light, radio waves, x-rays)
What is Electrical energy?
movement of electrical charges through a wire
What is energy?
the ability to do work or cause change.
What is the law of conservation of energy? (Hint: 4 parts)
-Energy is conserved when a change occurs. -Energy cannot be created or destroyed. -Energy can only be transformed (changed) into other forms of energy. -A lot of energy is transformed to heat. (friction or thermal energy)
Example of Electrical Energy:
-Light bulb -Lightning -Magnets -Power source
Example of Nuclear Energy:
-Nuclear power plants -The sun's energy is produced from a nuclear fusion reaction in which hydrogen nuclei fuse to form helium nuclei.
Example of Thermal (heat) Energy:
-Rubbing hands together to create friction which causes heat. -Standing by a fire
What are examples of Energy?
-Sun is the main source -Wind
Example of Electromagnetic (light) Energy:
-Visible light -X-rays, radio waves, and laser light. -Powerlines -Microwaves -Sun (UltraViolet)
What is Kinetic energy?
-energy in a moving object, -energy being released, (ex. arrow from a bow)
What is potential energy?
-energy that is stored, -energy waiting to be released
Example of Chemical Energy:
-fuel and food are forms of stored chemical energy. -wood burning -gasoline burning -energy used by the cells in your body (ATP)
Example of Mechanical Energy:
-kicking a football -throwing a bowling ball -putting a book on the shelf -turning a car key -riding a bike
What is the difference between potential energy and kinetic energy?
Kinetic energy is energy of motion; Potential energy is stored energy.
Which type of energy is produced by electrically charged particles?
Light (electromagnetic) Energy
Which type of energy is produced by moving objects?
Mechanical Energy
Example of Sound Energy:
Music
Which type of energy is stored in the nucleus of an atom?
Nuclear Energy
What are the two general types of energy that all energy forms can be classified under?
Potential and Kinetic Energy
Which type of energy describes the kinetic energy (average energy of motion of the particles) of matter?
Thermal (heat) Energy
