Solids

The Kinetic Theory of Matter

Differents forms of matter can on: solids, liquid and gas, they hace differents amount of energy.

Atoms

Are the basics building blocks of ordinary matter. Atoms can join together to form molecules, which in turn most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons.

Matter in Motion

Particles move bacause their hitt with others particles.

Chemicals produced by garbage

Trash  is the a big problem every dat and a drama for cities, citizens do not know what to do with so much garbage they are a source of bad smells, infections and diseases, and enviroment pollution.
In my case I will do somo robots that two or three days in a week will help us to pick up garbage beside the garbage trucks and they all ready pick the garbage up.
I think it would be a very good idea and it would also cause global warming to not happen as many changes as those that are suffering now and that is hurting us.

Types of energy



Energy is the ability to produce work. Energy can be found in many forms but are six forms of energy that are the most common use: electrical energy, kinetic energy, chemical energy, mechanial energy, potential energy and the last but not less important is gravitational energy, when yoy eat, the food gift you energy. You can see a form of energy in heat and ligth, when you walk the street lamps transmits you electrical energy. Kinetic ang potential energy are the main forms of energy, kinetic energy that is in motion and potential nergy is the energy stored in an object. Energy can neither be distroyed or created but it can transform from one form of energy to another, if an object have potential and kenetic energy is known as mechanical energy. Chemical energy is cause by virus chemical reactions, during the digestion process chemical energy is release when food is broke down. Electrical energy, where ever there is electricity is the electrical energy. Gravitational energy is the energy cause by gravity, an example can be when an object fall because of the gravitatioanl bulls. Plants use energy from sunshine during photosynthesis, only 10 porcent of energy in a light bulb is use to created light the other 90 porcent created heat.
