Energy - Coggle Diagram
Energy
Energy exists in different forms
ll forms of electricity cause change to occur
flow of electricity through wire causes a cool dark bulb to glow and get hot
Energy from wind causes a flag to flutter in the wind
Energy is the ability to cause change
Forms of energy
Mechanical energy
Energy that moves something
Sound energy
Vibration of particles in a solid liquid or gas
Chemical energy
Energy that is stored in the chemical composition of matter is chemical energy
Heat
Thermal energy
The total amount of energy from the movement of particles in matter is thermal energy
Electromagnetic energy
Electromagnetic energy is transmitted through space in the form of electromagnetic waves
Light
UV - Reindeer, Infared - Snakes, Night enhanced - Wolves
Nuclear energy
The center of an atom, its nucleus, is the source of nuclear energy
Kinetic energy and potential energy are the two general types of energy
Kinetic energy
Kinetic energy depends on a matters mass and speed which the object is moving
Kinetic energy increases as mass increases
Kinetic energy inceases as speed incease
Potential energy
Potential energy is the stored energy that an object has due to its position or chemical composition
A potential energy from is that results of gravity
Another form is stretching or compression
Chemical energy is also a form potential energy
Energy can change forms but is never lost
Energy changes forms
Energy is always conserved
Energy can not be created or conserved
In many instances it has appeared that energy has been lost but it has changed forms
Energy conversions may produce unwanted forms of energy
The useful amount of energy is almost always less than the total amount of energy
Energy efficiency is a measurment of usable energy after an energy conversation.
Technology improves the ways people use energy
Technology improves energy conversations
Efficient Lights
More efficient Lights conserve a lot more energy
Efficient cars
Devices Made to measure amount of gasoline used
Increase in distance to gasonline rate
Hybrid cars use gasoline and electric energy
Technology improves the use of energy resorces
Solar energy
Solar cells are made of several layers of light sensitive materials which convert sunlight directly to ejectricsl energy
Wind energy
Windmills and sails on ships and grind grain and pump water
Capturing wind to improve efficiency
WINDMILLS
