Types of energy
LIGHT ENERGY
Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up
-
TRAVEL
Light energy travels in the form of waves. Light energy is very fast – in fact, nothing travels faster
FORMED
When an object's atoms heat up, photon are produced from the movement of atoms. The hotter the object, the more photons are produced
-
USED
-
used by plants, which capture the light energy from the Sun and use it to produce their food
NUCLEAR ENERGY
is released by nuclear fusion (nuclei are fused together) or nuclear fission (nuclei are split apart)
-
FROM
released from an atom
Nuclear fission, when nuclei of atoms are split apart
Nuclear fusion, when nuclei of atoms are combined or fused together
-
-
ELECTRICAL ENERGY
-
The amount of energy depends on the speed of the charges – the faster they move, the more electrical energy they carry
GENERATED
In a nuclear power plant, nuclear energy heats water into steam. The steam is used to turn a turbine blade, which fires up a generator to give electric charges their energy.
In a hydroelectric plant, falling water is used to spin the turbine blades. The blades turn the generator to create electrical energy.
In a windmill, wind power turns the turbine blade, which makes the generator create electrical energy.
Solar energy is energy produced directly from the sun. Solar energy can be converted into electricity, or used to heat air, water or other fluids.
EXAMPLE
In a car battery, a chemical reaction creates an electron. These moving charges provide electrical energy to the circuits in the car
During a thunderstorm, lightning is electricity in the atmosphere being discharged
Electric eels generate electrical energy, which they use to defend against predators and to stun their prey.
MOTION ENERGY
-
-
"WORK"
when a force acts on an object and causes it to move, change shape or position, or do something physical
-
SOUND ENERGY
-
TRAVEL
-
sound cannot travel through a vacuum, because there are no atoms to transmit the vibration
can be transmitted by solids, liquids and gases, as these all have atoms to pass on the vibrations
-
-
-
THERMAL (HEAT) ENERGY
produced when a rise in temperature causes atoms and molecules to move faster and collide with each other
Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
HOW?
When a substance heats up, the rise in temperature makes these particles move faster and bump into each other
The hotter the substance, the more its particles move, and the higher its thermal energy
-
RADIANT ENERGY
-
THE SUN
produces a lot of radiant energy, which is transmitted to Earth as light
-
-
GRAVITATIONAL ENERGY
-
-
CAUSES
Systems can increase gravitational energy as mass moves away from the centre of the Earth or other objects that are large enough to produce significant amounts of gravity
CHEMICAL ENERGY
energy stored in the bonds of chemical compounds, like atoms and molecules
When a chemical reaction takes place, the stored chemical energy is released. Heat is often produced as an exothermic reaction.
is the most widely used type of energy in the world, as it is crucial to the existence of humans and the natural world
EXAMPLES
Chemical energy in food
As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created
keeps us warm, helps us move, and allows us to grow
Chemical energy in wood
When burn that wood in a fireplace, chemical energy is released and converted into thermal energy (heat) and light energy
