3rd grade: History of the World - #1d creation forces in action

When God moved, resonance and time started, law came to all things and so many things happened. When he moved he made energy.

Energy Resources and Energy Transfer

BBC Schools: Energy basics

Energy allows things to happen. If you leap around wildly, people often say that you have lots of energy. Energy allows you to move around and keep warm. It allows you to see and to hear. Energy cannot be created out of thin air or destroyed - it can only be stored or transferred from place to place in different ways. Let's look at some examples.



Image: a childs drum


The vibrating drum and the plucked guitar string transfer energy to the air as sound. This sound energy can be transferred to your eardrum as kinetic energy (movement energy).


Image: battery and bulb


The battery transfers stored chemical energy as electrical energy in the moving charges in the wires. The electrical energy is transferred to the surroundings by the lamp as light energy and thermal energy (heat energy).

Image: a rock balancing on the top of a mountain


The rock on the mountain has stored energy because of its position above the ground and the pull of gravity. This energy is called gravitational potential energy. As the rock falls to the ground, the gravitational potential energy is transferred as kinetic energy.

A cup of hot tea has heat energy in the form of kinetic energy from its particles. Some of this energy is transferred to the particles in cold milk, which you pour in to make the tea cooler.

Image: explosive


When the explosive goes off, chemical energy stored in it is transferred to the surroundings as thermal energy, sound energy and kinetic energy.

Genesis 1

1In the beginning God created the heaven and the earth.

2And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.

3And God said, Let there be light: and there was light.

4And God saw the light, that it was good: and God divided the light from the darkness.

5And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
