Kinetic Energy & Thermal Energy

Chemical Energy

1 J = 0,24 cal1 cal = 4,18 J

1 joule = 0,24 calories1 calorie = 4,18 joules

We use joules (J) to measure Energy.But we can also use calories (cal) to measure the Chemical Energy stored in food and drinks.

HOW CAN WE MEASURE ENERGY?

Radioactive metal found in rocks

Uranium

Mixture of gases formed from decayed living organisms

gas

Natural

Black rock composed mainly of carbon

Coal

It's the source of the fuel oil, diesel fuel and petrol

Petroleum

Non-Renewable

From plant and animal products

Biofuels

From the Sun in the form of light and heat

energy

Solar

From the movement of air

energy

Wind

From water that is moving or falling

energy

Hydroelectric

Renewable

ENERGY SOURCES

separate rubbish and put it in the correct bin

Recycle

use glass, metal and plastic containers again and again

Reuse

buy products that don't have a lot of packaging

Reduce

The three Rs
