  • The meaning of Energy

Energy is the ability to do work. Where there is growth, movement. or change, there is energy. Ail people have energy. Plants ana animals nave it, too. Machines, both big and small, also have energy.

What would our world be like without energy? Nothing move. Nothing would grow.There would be no light, no warmth. no sound. There would be no people. no plants, no animals. We would have a dead. still world.

But we do have energy-and we get it from the sun.

  • Indirect Energy

    How do plants, animals and ourselves get energy from the sun? The light and heat of the sun help to make plants grow. The sun's energy is Stored in the plants. We eat food that comes from, these plants. We eat food that comes from the animals which eat the plants.

Some examples of these kinds of food are rice, bread and meat. Rice comes from a plant. Bread is made from flour. Flour is made from wheat, which, in turn, is the seed from a plant. Meat comes from animals that eat plants or their fruit or grams. Thus, animals and ourselves get energy from 1he sun everytime we eat.

How do machines get energy from the sun? Some machines- cars, trains, airplanes, and others-burn fuel like oil, gas, or coal. These fuels come from deep inside the earth. For example, we dig mines to get coal..We dig wells to get oil or gas. How did these fuels get into the earth?

All fuels were living plants and animals once. While they were living they got their energy from the sun. When they died. they became part of the soil. Over the years. they were pressed farther and farther down into the earth. As they were pressed farther clown, the heat of the earth worked on them and changed them into fuel. And where did the heat of the earth come from? It came from the sun! So the fuel that makes machines go is really energy from the sun.

Was the sun used directly to give energy? No, it was not. What was used was the result of the light and heat of the sun which was stored in the plants, the animals, and the fuel. What was used was indirect energy.

  • Direct Energy

Today, scientists are looking for ways to capture the rays of the sun 1or direct use. One of these is to capture and store the heat to make electricity. This is called solar energy. Some time pieces and calculators today are run by solar energy. A few people have experimented with the use of solar energy to light their homes and IQ run household appliances like refrigerators. Indeed since the sun shines in our country most of the time, we could use solar energy or direct energy to lessen our dependence on imported fuels.

All people do have energy, one can actually absorb energy from someone and it's called "looshing". Some people say that looshing is a negative thing because it's wrong to absorb energy from a person. Loosh can be positive energy and not just negative energy. There are many conspiracy theories out there about loosh and "energy vamps" or energy vampires. Some say those that are reptilian minded like to loosh energy.

Your article regarding energy is good, but I need to make a correction: the energy used by machines is called Mechanical Energy. It is the energy possessed by an object(machine) by virtue of its motion or rest position. It is divided into two:

  1. Kinetic Energy: Energy by virtue of motion of the object- KE=œmv² m= mass, v= velocity.
  2. Potential Energy: Energy by virtue of rest position of the object- PE= mgh. m= mass, g= gravitational acceleration, h= distance. Thanks.

There are many types of energy in the world. Heat energy, solar energy, wind energy and electricity are some of them. It is impossible for us to survive without all these forces.
