Energy Examples
The sun fuses hydrogen atoms together into helium to produce light and heat
Nuclear, light and thermal
A lit up "exit" sign is the only reason you can see in a windowless room after a blackout
Light Energy
A toaster
Electrical energy --> Thermal Energy
A hamster runs on a wheel lighting up a light bulb
Mechanical --> Electrical
A hockey puck hitting the wall
Mechanical energy to swing the stick / move the puck
Sound energy of hitting the board
Thermal energy of friction with ground/board
The reason why you can see anything
Light Energy
A nuclear explosion is triggered by the breaking of bonds in certain types of atoms
Nuclear Energy
Photosynthesis
Light Energy --> Chemical Energy
A nuclear bomb
Nuclear --> Light and Thermal Energy
Pushing a ping pong ball across the room by blowing through a straw
Chemical energy --> Mechanical Energy --> Mechanical energy
A lamp is plugged into a wall outlet. The electric current moves from the wall outlet into the light bulb in the lamp supplying electrical energy. When the electric charges slow down in the filament to light the light bulb, light energy is created.
Electrical Energy
A spinning windmill possesses it
Mechanical Energy
The moving human body
Chemical Energy --> Mechanical Energy
Water is heated, and the steam rises up and turns a turbine
Thermal --> Mechanical
Breaking a hand warmer
Chemical --> Thermal
A hot cup of steaming cocoa contains this
Thermal Energy
Lightning is generated by a thunderstorm
Electrical Energy
A cue ball hits the 8-Ball
Mechanical --> Mechanical
(or thermal)
Seeing a lightning bolt
Electrical Energy --> Light Energy
Holding your hand over a static electricity generator
Electrical Energy --> Mechanical Energy
An arrow flying through the air towards the target
Mechanical Energy
Infrared goggles are used to see the outlines of human bodies in a color-coded way
Thermal Energy
You stomp your foot
Mechanical --> Sound Energy(Also mechanical sort of)
Raising your hand in class
Nuclear Energy(sun) --> Light energy --> chemical energy (photosynthesis) -->chemical energy (eaten by a cow) --> chemical energy (eaten by a human) --> Electrical Energy (Brain uses energy to fire off a signal) --> mechanical energy to raise your hand (message from brain received)
Getting cattle-prodded
Chemical --> Electrical --> Electrical, Light and Thermal Energy, Light Energy
