The Work of Energy In Physics

The ability of a system to do work is called energy and Special Relativity shows that energy has mass and that the mass of all matter is a result of energy, so that all substance is based on energy. The 1st Law of Thermodynamics states that the energy in any interaction is conserved. The result is that is the total amount of energy in the universe is constant. It is also stated as energy can not be created or destroyed but it can change forms.

Here are some common types of energy. Heat energy is the energy associated with the temperature of an object. Light energy is the energy associated with visible light. Electrical energy is the energy associated with an electric current. Chemical energy is the energy associated with the reactions involving molecules. Nuclear energy is the energy associated with reactions involving atomic nuclei. Kinetic energy is the energy associated with motion.  Potential energy is the energy of a system based on its position or condition. Stored energy. Rest mass energy is the energy of an object that is not in motion. E= mc2.

Energy is one of the three main parts of the Universe space, time and mass and relativity shows them to be inter-related. Space and time are so interrelated that they form a single entity. Furthermore mass warps space-time forming Gravity and the motion of mass contracts both space and time. 

In conclusion in common experience energy is what moves us and allows us to move thing. Physics has shown it to be a lot more. It is a fundamental part of the universe.

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.
