chapter 3 energy
3.2 energy can change forms but is never lost
energy can change forms
conversions between potential energy and kinetic energy
using energy conversions
energy is always conserved
the law of conservation of energy states that energy can neither be created nor distroyed
energy conversions may produce unwanted forms of energy
energy efficiency is a measurment of usable energy after an energy conversion
technology improves the ways people use energy
technology improves energy conversions
efficient lights
efficient cars
technology improves the use of energy resorses
solor energy
solar cells are made of several layers of light sensitive materials Which convert the sun directly into electrical energy
wind energy
3.1 energy exists in different forms
different forms of energy have different uses
forms of energy
chemical energy
thermal energy
sound energy
electromagnetic energy
mechanical energy
nuclear energy
energy
energy is the ability to cause change
kinetic energy and potential energy are the two general types of energy
kinetic energy
the energy of motion is called kinetic energy
kinetic energy increases as mass increases
kinetic energy increases as speed increases
potential energy
potential energy is the stored energy that an object has due to its position of chemical composition
