Energy is all around us.

Scientists define energy as the ability to do work or cause change.

We cannot see energy, but we can see the things that energy does.

energy makes things move it powers the machines we use it can make things get hotter

or produce sound energy is used to light up our homes

and cities and power the vehicles we use all organisms need energy to grow reproduce and carry out life processes.

Plants use the light energy from the sun to make food in the form of sugar.

This energy is passed to animals when they feed on plants and other animals.

There are two main forms of energy, kinetic energy and potential energy.

Kinetic energy is the energy of movement.

Mechanical energy, sound, light, heat and electrical energy are all examples of kinetic energy.

You can learn more about these forms of kinetic energy in our related videos.

energy is the energy something has due to its position, composition or state.

The stored energy can be converted into various types of kinetic energy.

Fuels such as petroleum, gas and wood contain a form of potential energy called chemical energy.

When these fuels are burned, the chemical energy is converted into light and heat.

Potential energy due to an object's position above the ground is called gravitational potential energy.

A rock on top of a hill has gravitational potential energy.

As it rolls down the hill, the potential energy is converted into kinetic as it is pulled down by the earth's gravity.

An arrow in a bow has potential energy due to its position behind the drawn string.

This is called Elastic Potential Energy.

The elastic potential energy increases the more the string is drawn back.

When the string is released, the potential energy is converted into kinetic energy as the arrow flies forward.

That's pretty cool.

Be sure to check out our related videos to learn more about different energy forms and conversions.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
