Energy Transfer and Efficiency | GCSE Physics | Doodle Science

Doodle Science teaches you high school physics in a less boring way in almost no time!

Different types of energy can be transferred from one type to another. You can see that a car engine transfers chemical energy, which is stored in the fuel, into kinetic energy in the engine and wheels so it can get you from A to B. In a lamp the electrical input is converted into light energy. However not all the energy put in is turned into useful energy, some of it is turned into energy we don’t need such as heat.

Sankey diagrams summarise all the energy transfers taking place in a process. The thicker the arrow, the greater the amount of energy involved. This Sankey diagram for an electric lamp shows that most of the electrical energy is transferred as heat rather than light. This means it’s very inefficient. We can calculate efficiency using this simple formula, useful energy, in this case 10J divided by the total energy input, which is 100J, which gives us an efficiency of 0.1 or 10% if you times it by 100.

Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate.

The wind is produced as a result of giant convection currents in the Earth’s atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there’s no electricity.

Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.

Fossil fuels are non-renewable energy resources; these are coal, oil and natural gas. They were formed from the remains of living organisms millions of years ago and they release heat energy when they are burned. This heat is used to turn water into steam, which is used to turn a turbine, which then drives a generator to generate electricity. There are downsides however, fossil fuels release sulphur dioxide and carbon dioxide which lead to acid rain and an increase in global warming.

Another form of non-renewable energy is Nuclear. The main nuclear fuels are uranium and plutonium. The nuclei of these large atoms are split in a process called nuclear fission to release a great deal of heat. The heat energy is again used to boil water. The kinetic energy in the expanding steam spins turbines, which then drive generators to produce electricity. Unlike fossil fuels, nuclear fuels do not produce carbon or sulphur dioxide. However, they do have the risk of a fault where large amounts of radioactive material could be released into the environment such as the disaster of Chernobyl in 1986.

Keep going! Check out the next lesson and practice what you’re learning:

Passive solar energy systems absorb heat directly from the sun without the use of mechanical and electric equipment, and energy cannot be collected or stored. Active solar energy systems use solar energy to heat a liquid through mechanical and electric equipment to collect and store the energy captured from the sun. Photovoltaic solar cells capture light energy from the sun and transform it directly into electrical energy. Their use is limited by the availability of sunlight.

About us:
Welcome to Tutway.
A unique platform where learning is fun.
Now there is no distinction between kids’ fun time and study time.
At Tutway, we believe in a very simple idea that audio-visual learning is the most effective tool for grasping knowledge. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons as compared to reading from books.

That’s when Tutway comes to the rescue.
Tutway is a supplementary education program where kids can learn at their own pace. The students can watch animated videos that are so meticulously made that they can understand even the most complex concepts very easily. There is a question bank at the end of each video where students can answer those questions multiple times and test whether they have grasped knowledge completely or not.
We have information systems embedded in the program where parents can monitor real-time performance of their kids and get up to date information about their performance, including quizzes attempted and the marks got in each quiz, both in tabular and graphical formats. Regular reports are e-mailed to the parents so that the parents can analyze their kids’ performance.
If we want to learn high-level concepts, we should have a clear understanding of the basic concepts. For instance, if kids don’t know about addition and subtraction, they cannot do multiplication, and if they don’t know about multiplication, they cannot do division, and if they don’t have knowledge of these four basic operations, Algebra cannot be done by them, and it goes on and on.
The same applies to the English language if kids don’t have sound knowledge of grammar and vocabulary; it becomes extremely difficult for them to have their communication skills.
Knowledge of the scientific concepts is also required for observing physical, chemical, biological phenomena happening all around us.
That is why; Tutway has thousands of animated videos on Maths, English, and Science to clear the basics of these subjects. It perfectly suits most of the educational needs of most of the students, regardless of their learning abilities.
So hurry up, download the Tutway app and book a free demo class to make education interactive and fun experience.
