 Hello! Today's episode is about electricity. Electricity relies on the idea of electrons. Electrons is a subatomic particle - a particle which makes up of an ato . It has a negative charge and there are sixteen of them in a single atom. So how do they relate to electricity? Electricity is a physical phenomena where something moves that has an "electric charge". This idea of electricity is related to magnetism, because it is related to movement. Simply, it is a type og energy that consists of the movement of electrons. Electricity generates an electric current, and things can conduct electricity to make it move faster and insulate it to make it slower.

 Hello!  Heat - Heat is an energy that is transferred from one body to another because of a difference in temperature. Heat flows from hot bodies to cold bodies ("bodies" meaning objects or matter). Hear energy is created when aroms move faster and collidep. It is also known as thermal energy, and heat is the transfer of said energy. Light - Light is a kind of radiation that can be perceived by the human eye. It has wavelengths which can differ, forming what we know as colors. It can travel, refract, reflect, diffract, interfere, and disperse, etc. These things is possible by light.

 Hello! Today is about matter and energy, and the second week of the Physics series. What is Matter? Matter is a physical substance which occupies space and has mass, distinct from energy. Matter is physical, so it does not have a rational nor conscious nature, at least itself. The popular understanding is that there are three states of matter, which is true, though there are other things considered as states of matters, the most popular of which being plasma. Basically, matter is a physical object. But it says "distinct from energy". What is energy, then? What is Energy? Simply, energy is a capacity to do something, especially moving something else. Energy falls into two central categories: kinetic energy and potential energy. What is the difference between the two types? Kinetic energy is in movement, while potential energy is not used, but usable to work.

 This is the second week of our ScienceForDummies new format and we are entering a 4-term period where we discuss particularly physics. This week will just be an introduction on the question "what is physics?". the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity,  magnetism , and the structure of  atoms . That is the standardized definition of the word "Physics". Let's break the paragraph-long definition down and explain it. "the branch of science" is fairly practical - basically a kind of science. "concerned"  can mean "relating to" and "about". "with the nature and properties" means it is about how something is - its nature - and its particular features - its properties. "of matter and energy" means about matter - whic...
