Types of Energy
Energy that travels in waves and can move through space
Light energy
The capacity to do work
Energy
These waves of light are visible
Visible light
Rapid back and forth motion of air or other matter.
This is an example of light energy being converted into chemical energy
Photosynthesis
Energy carried by electrons
Electrical energy
A force applied to an object which causes the object to move
Work
These waves of light energy have the largest wavelength
Radio waves
A way of talking at a high frequency that can't be heard far away
Whispering
This is an example of light energy being converted into electrical energy
Solar Power
Energy stored in the bonds between atoms and molecules
Chemical Energy
Which has more potential energy?
A diver on a board 10 meters in the air
or
A diver on a board 15 meters in the air
A diver on a board 15 meters in the air
These waves of light have the highest frequency
Gamma waves
What kinds of sounds can be heard the furthest away?
Low frequency sounds
This is an example of electrical energy being converted to light energy
A lightbulb
Stored energy that an object has due to its position or internal stress
Potential Energy
Who did more work? (TRICKY)
A student lifting a 5kg weight 1m high 5 times
A student lifting a 50kg weight 1m high once
They both did the same amount of work :P
Frequency
The distance between two identical points in a wave
Wavelength
This is an example of potential energy being converted into kinetic energy and sound energy
A balloon popping
Energy formed when an atoms splits apart or fuses with another atom.
Nuclear Energy
Which has more kinetic energy?
A rock that weighs 500 kg moving at 10 m/s
or
A rock that weighs 50kg moving at 100 m/s
The second rock that weighs 50kg moving at 100 m/s
The speed of light in meters per second
300,000,000 meters per second or 3 x 10^8 m/s
The speed of sound in Earth's atmosphere per second
340 meters per second
This is an example of chemical energy being converted into heat energy which is converted into kinetic energy and then converted into electrical energy
A fossil fuel power plant
