Energy
3.1
Different forms of energy have different uses
Energy
forms of energy
sound energy
mechanical energy
the energy that moves objects is mechanical energy. The energy you use to put a book on a shelf is mechanical energy, as is the energy that a person uses to turn a car key
Sound results from the vibration of particles in a solid, liquid, or gas. people and other animals are able to detect these tiny vibrations with structures in their ears that vibrate due to the sound. So when you hear a car dive past, you are detecting vibrations in the air produced by sound energy
chemical energy
energy that is stored in the chemical composition of matter is chemical energy. The amount of chemical in a substance depends on the types and arrangement of atoms in the substance
thermal energy
The total amount of energy from the movement of particles in the matter is thermal energy. Recall that matter is made of atoms and atom combined in molecules.
Electromagnetic energy
Electromagnetic energy is transmitted through space in the form of electromagnetic waves. Unlike sound, electromagnetic waves can travel through empty space.
Nuclear energy
The center of an atom its nucleus is the source of nuclear energy.
Kinetic energy and potential energy are the two types of energy
The energy of motion is called kinetic energy
kinetic energy increases as mass increases. If a bowling ball and the soccer ball were moving at the same speed, the bowling ball has more kinetic energy because of its greater mass
Kinetic energy increases as speed increases. If two identical bowling balls were rolling along at different speeds, the faster one would have more kinetic energy because of its greater speed.
potential energy
potential energy is the stored energy of that object's has due to its position or chemical composition
3.3
technology improves energy conversions
efficient lights
Research to replace lights bulbs with a more energy-efficient has resulted in the light emitting diod or led
efficient cars
another common but inefficient energy conversion is the burning of gasoline in cars. A large percentage of gasoline's chemical energy is not converted into the car's Kinetic
technology improves the use of energy resources
much of energy used on Earth comes from fossil fuels
wind energy
for many centuries, people have used the kinetic of wind to sail ships and,

energy changes forms
conversions Between potential energy and kinetic energy
The results of some energy conversion are obvious, such as when electrical energy in a light bulb is changed into light and heat. Other energy conversions are not so obvious.
A match may not appear to have any energy by itself, but it is does contain potential energy that can be released.
energy is always conversions
when you observe energy conversions in your daily life, it may seem that energy constantly dispears after all, if you give a soccer ball
laws of conservation of energy states that energy can neither be created
