Energy By the one who knows

Work Energy is the ability to do work

Energy Conservation Energy can not be created or destroyed but only changed from one form to another Dont tell the poor sods in Hiroshima and Nagasaki that.

Forms of Energy There are many types of energy and most actions are a conversion of energy from one form to another.

Solar Energy Energy we get from the sun as radiation

Kinetic Energy Energy a body has because it is moving

Potential Energy The energy that something has due to its position or condition High up Wound up

Chemical Energy Energy stored in fuel and food.

Electrical Energy Both from batteries and the mains and…

Nuclear Energy Energy contained in the atom (Holding the nucleus together)

Heat Energy Energy due to temperature of the body. (The movement of the molecules)

Sound Energy Any kind of noise or music is waves of compressed air. It needs a medium to travel in.

Light Energy Another type of wave that does not need a medium. Travels in straight lines Can be REFLECTED by a mirror And REFRACTED by a Lump of glass

Nuclear Light Sound Chemical Potential Kinetic Heat Solar Electrical

Electrical Energy Heat Energy + Sound Energy

Nuclear Light Sound Chemical Potential Kinetic Heat Solar Electrical

Chemical Kinetic + Sound Potential

Nuclear Light Sound Chemical Potential Kinetic Heat Solar Electrical

Chemical Heat Kinetic + Light + Sound

Your Turn i-pod Motor car Hydroelectric Dam Light Bulb

Non-renewable Fossil Fuels Limited and usually made 100 million years ago Coal- Pressed trees Oil – dead sea creatures Gas – rotted vapour of above

Renewable Im tired you have to do this……. List all renewable energy sources…. h/w p
