Physics
The Physics is a quantitative science that includes mechanics, thermal phenomena, electricity and magnetism, optics and sound. These matters are a part of the classic Physics. If in the resolution of a physical problem they must be considered to be speeds near to that of the light or sizes comparable to those of an atom, then there must be born in mind the beginning or laws of the modern Physics, this is, the discoveries of the century xx. This beginning includes the relativity and the quantum mechanics.
Is all that that has spatial location, possesses a certain quantity of energy, and is subject to changes in the time and to interactions with devices of measure.  

It is known that the atoms are the minimal unit of a substance, which composes the entire common and ordinary matter. If the atoms of a substance divide, the identity of such this one can be destroyed and every substance has the quantities different from the atoms that compose it 

is the transformation of the numerical value of a physical magnitude, expressed in a certain unit of measure, in another numerical value equivalent and expressed in another unit of measure of the same nature 

They are segments of straight line orientated it has three important characteristics. Magnitude. This is the numerical value with his respective unit. These units are physical as  
Free fall is a vertical motion in which the acceleration of the object is gravity, which is given a positive sign as it helps the movement and has an average value of 9.8 m / s ^ 2 or of 32ft / s ^ two. 

The rectilinear uniformly intensive movement (MRUA), also known as rectilinear uniformly varied movement (MRUV), is that one in which a mobile moves on a straight path being submitted to a constant acceleration 

Free fall is a vertical motion in which the acceleration of the object is gravity, which is given a positive sign as it helps the movement and has an average value of 9.8 m / s ^ 2 or of 32ft / s ^ two. 

Called parabolic movement made by an object whose trajectory describes a parabola. It is a movement upward and straight  
3 law  
Ohm’s law  Ohm's Law states that the intensity of the current flowing between two points of an electrical circuit is proportional to the voltage between said points. This constant is the electrical conductance, which is the inverse of the electrical resistance. 
It is the action of a force (F) on a body and thus moving its point of application a displacement r. The work is the symbol T.
