In other words, this law means that energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.

  • conduction

  • convection

  • radiation


Conduction

When a substance is heated, its particles gain energy and vibrate more vigorously. The particles bump into nearby particles and make them vibrate more. This passes the thermal energy through the substance by conduction, from the hot end to the cold end.


Convection

The particles in liquids and gases can move from place to place. Convection happens when particles with a lot of thermal energy in a liquid or gas move, and take the place of particles with less thermal energy. Thermal energy is transferred from hot places to cold places by convection.


Radiation

All objects transfer thermal energy by infrared radiation. The hotter an object is, the more infrared radiation it gives off.

Thermal energy is what we call energy that comes from heat. A cup of hot tea has thermal energy in the form of kinetic energy from its particles. Some of this energy is transferred to the particles in cold milk, which you pour in to make the tea cooler.

Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.

  • The word energy comes from the Greek word energeia.
  • Most types of energy are either a form of kinetic energy or potential energy.
  • Common examples include heat energy, elastic potential energy, chemical energy, sound energy, nuclear energy, geothermal energy and gravitational potential energy.
  • Kinetic energy refers to the energy an object has because of its movement. A car in motion has kinetic energy, as does a basketball when you pass or shoot it.
  • Energy can be transformed from one form to another. In lightning, electric potential energy transforms into light, heat and sound energy.
  • The law of conservation of energy states that energy can only be transformed, it can’t be created or destroyed.
  • You might have heard of Albert Einstein’s famous formula E = mc² (energy equals mass multiplied by the speed of light squared).
  • Food contains chemical energy which is used by living organisms such as animals to grow and reproduce. Food energy is usually measured in calories or joules.
  • Wind farms contain large numbers of wind turbines which are used to transform wind energy into a useful energy such as electricity. The use of wind power to generate electricity doubled between the years 2005 and 2008. More wind energy facts.
  • The USA's Mojave Desert is home to the world's largest solar power plant. More solar power facts.
  • The Three Gorges Dam in China is the world's largest hydroelectric power station. More hydropower facts.
  • Nuclear power produces around 13% of the world's electricity. More nuclear power facts.
  • Plants use energy from sunlight during an important process called photosynthesis.
  • A person standing on a diving board above a swimming pool has gravitational potential energy.
  • During chemical reactions, chemical energy is often transformed into light or heat.
  • Stretched rubber bands and compressed springs are examples of elastic potential energy.
