What's Matters in Physics

Anything that has mass and occupies volume is called Matter:. In general it is the substance of which all physical objects are made. Mass is in the generally sense it is the amount of matter in an object. It is the term for two properties of matter that are equal in value: inertial mass gravitational mass. Inertial Mass is the resistance of a body to acceleration when responding to force. Gravitational Mass is  the property of an object that determines the strength of its gravitational field and its reaction to gravity.

The existence of a relationship between the inertial and gravitational mass of an object is evident from the fact that they have same the value. However General Relativity shows that inertial and gravitational mass are two aspects of the same thing. Special Relativity shows that an objects mass is equivalent to the amount of energy an object contains.

Normal Matter is composed of atoms. Atoms are a nucleus; made of protons and neutrons; with electrons around it. This form of matter in what we commonly experience. Matter makes up everything around us, everything we see, everything we touch and even our bodies. Matter is one of the three main parts of the Universe Space, Time and Mass. (matter) Relativity shows them to be inter-related in that space and time are so interrelated that they form a single entity called space-time. Furthermore mass warps space-time forming gravity and the motion of mass contracts both space and time. In common experience matter is what makes up objects around us and Physics has shown that it to be a lot more. Matter is a fundamental part of the universe.

Space Its More than the Final Frontier

The three dimensional extent in which objects and events occur with a relative position to other objects and events is called space. In a more general sense space can refer to an nth dimensional hyper-volume. The notion of higher dimensions has gained more acceptability in physics with M-Theory. This opens the door to possibilities such as the supernatural that are usually considered out side the realm of science.

Often illustrated by 3 lines representing the three dimensions of space are the lines of  the axis of a 3d graph. In 3d space you can move in 3 directions forwards and backwards; up and down and left to right. General Relativity depicts space and time as a fabric that can be warped, bent, twisted, stretched and contracted. Quantum Mechanics describes subatomic particles coming and going even in a vacuum. Space is not empty, it is not nothing. Yes I am well aware that  this is a double negative however empty space is normally thought of as nothing but it is something.

Basic SI unit – meter (m) which is the distance traveled by light in a vacuum in 1/299,792,458 of a second. The most common methods of measuring space are rulers but odometers are another common way of measuring distance and there by space. Other methods include bouncing light, radio waves, or sound off of an object using the return time to measure distance. These include radar and sonar. Parallax uses geometry to measure distance it is used in Astronomy and land surveying.

Distance and position must be measured according to some standard. The standard has to be a chosen point in space. The point is selected by ether convenience or convention with out such a starting point determining distance and position is impossible..

Space is one of the three main parts of the Universe space, time and mass. Relativity shows them to be inter-related with space and time are so interrelated that they form a single entity.  Intern mass warps space-time forming gravity and motion of mass contracts both space and time. Based on common experience space is basically where you are. You are at a particular point in space relative to other objects. Physics however has shown it to be a lot more. It is a fundamental part of the universe.

Now It’sTime for Physics.

The observed sequences of events is called time. In physics it is seen as a 4th dimension

Time‘s basic SI unit for is the second. Its duration is defined as a 9,192,631,770 periods of the radiation of the transition between the two hyperfine levels of the ground state of the cesium133 atom. It was originally defined based on a day. The week is the only time unit not based on an astronomical period being based on the Jewish Sabbath cycle which is based on the creation week of Genesis 1.  The calendar year is rounded to 365 days with a leap day every 4 years.

According to Special and General Relativity time is a 4^th dimension. It is unique in that we only travel through time one way. (forward).  Time is one of the three main parts of the Universe: space, time and mass. Relativity shows them to be inter-related with space and time are so interrelated that they form a single entity.  Mass warps space-time forming gravity and motion of mass contracts both space and time.

We perceive the rate of time as variable but time is always experienced in the same way. We remember the past, we exist in the present and we look forward to the future. In our common experience time is the sequence of events we experience. Physics has shown that it is to be a lot more. It is a fundamental part of the universe.
