Chapter 9 Study Guide

This is when atoms split and give off energy.

Work, like energy, is expressed in ?????

a nonrenewable: coal, natural gas, and petroleum.

Plants use light energy to make new substances that have chemical energy.

They are used to make kerosene, wax, and plastic.

Organic matter such as plants, wood and waste that can burned to release thermal energy.

Convert the chemical energy in fossil fuels into electrical energy.

a natural resource that can be replaced at the same rate at which the resource is consumed.

are more efficient when they use less energy.

The ability to do work

The energy of an object that is due to the objects motion

The energy that an object has because of the position, shape, or condition of the object

When you lift an object, you do work on it

The amount of work an object can do because of the objects kinetic and potential energies

The kinetic energy due to the random motion of the particles that make up an object

This is a form of potential energy

Starting with coal which is a chemical & potential then burn it, Thermal which is (kinetic)

Burn water to create steam which is forced thru pipes in turbines making it spin and thats mechanical

Then go to the electricity

Then turn on the light (electrical) or blow dryer (thermal, mechanical, and sound)

Energy that comes from changes in the nucleus of an atom

This is when atoms split and give off energy

The energy of moving electrons

Vibrating objects transmit energy through the air around them

Energy produced by the vibrations of electrically charged particles

A change from one form of energy to another

states that energy cannot be created or destroyed (energy is never lost) but can be changed from one form to another (just changes forms)

Is a natural resource that cannot be reused or replaced

Convert the chemical energy in fossil fuels into electrical energy

a natural resource that can be replaced at the same rate at which the resource is consumed

sunlight is changed into electrical energy through solar cells

falling water from a dam turns a turbine which is connected to an electric generator

The kinetic energy of the wind turns blades of a windmill which turns an electric generator

Thermal energy caused by the heating of Earths crust

Organic matter such as plants, wood and waste that can burned to release thermal energy
