What is Energy?
Energy is one of the most fundamental parts of our universe.
We use energy to do work. Energy lights our cities. It powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, and gives us pictures on television. It powers machinery in factories and tractors on a farm.
Energy from the sun gives us light during the day. It dries our clothes when they’re hanging outside on a clothesline. It helps plants grow. Animals, giving them strength, stored in plants. And predator animals eat their prey, which gives the predator animal strength.
Everything we do is connected to it in one form or another.
Energy is defined as: “the ability to do work.”
When we eat, our bodies transform the stamina stored in the food into energy to do work. When we run or walk, we “burn” food energy in our bodies. When we think or read or write, we are also doing work. Many times it’s really hard work!
Cars, planes, light bulbs, boats and machinery also transform vitality into work.
Work means moving something, lifting something, warming something, lighting something. All these are a few of the various types of work. But where does it come from?
There are many sources of stamina. In The Energy Story, we will look at the strength that makes our world work. Power is an important part of our daily lives.
The Forms of Energy We Will Look at Include:
-Fossil Fuels – Coal, Oil and Natural Gas
-Hydro Power and Ocean
This is vital part of our life, we need it survive and to do day-to-day activities. Next time you turn on a light bulb think about where it all started.
