KS4 Types of Energy

What is energy? Energy lets you do things. Another name for energy is ____ work The units of energy are ______. Joules There are many different types of energy you need to know about. How many joules in a kilojoule? _______ 1 000 J

Different types of energy Light ___________ Sound Kinetic Nuclear Energy Electrical Chemical Elastic Gravitational Heat

Light energy Light is a type of electromagnetic radiation. Light travels in straight lines. Light travels in transverse waves. Light transmits ENERGY. Our Sun (a star) is a light source, just like a filament lamp or a firefly. Which colour of light has the most energy, red or violet? How do we see the planets? By reflected light. violet

Sound energy Sounds are caused by v_______. ibrations Sound travels in l_________ waves. Sound transmits e____. The l_____ the sound, the more energy it transmits. The q_____ the sound, the less energy. ibrations ongitudinal nergy ouder uieter

Heat energy The hotter an object is, the more heat or thermal energy it has. Electrical devices use the fact that as electrons flow along a conductor, friction between the electrons and the conductor’s atoms occurs. Whenever you get friction you get heat, so the movement of electricity generates heat energy. Some devices that are designed to produce heat energy are: ________ ___________ Kettles Toasters Electric fires

Electrical energy This is the energy electrons have as they flow around a circuit. Electricity is so useful because it is such a convenient way to transfer energy to a desired location or to a desired device. What happens when the switch is closed? Electricity flows and the bulb lights.

A Jack-in-the-box stores elastic energy If you squash or c_______ an object or material, when you let go some materials have the p_______ to return to their original shape. We call the energy stored in a squashed or compressed material e_____ energy. The same is true for materials that are s_______ (put under t_____) they too have the potential to return to their original shape. They too store elastic energy. ompress A Jack-in-the-box stores elastic energy otential Boo!!!! lastic tretched ension Press

Chemical energy When chemical bonds are broken they can release energy. The energy stored in these chemical bonds is referred to as chemical energy. The three sources of chemical energy you need to know about are: ___________ Food Batteries Fuels

Gravitational energy Any object in a gravitational field has gravitational potential energy due to its position in that field. The _____ has gravitational potential energy due to the gravitational field of the Earth. Moon The ____ has gravitational potential energy due to the gravitational field of the Sun. Earth

Changes in gravitational potential energy For an object in Earth’s gravitational field: If an object falls will it gain or lose gravitational potential energy? If an object moves up will it gain or lose gravitational potential energy?
