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.

Thermodynamics in Physics

Thermodynamics is the study in physics that deals with the transfer of energy, the work done by it and the affect on matter. Thermodynamics is dynamic and not kinetic so it is not concerned with the actual energy movement processes. Thermodynamics deals with the results of energy transfer.

There are two main fields of Thermodynamics Classical Thermodynamics and Statistical Thermodynamics.

Thermodynamics was developed as a result of the study of steam engines and was based entirely on empirical measurement and it lead to the four laws of Thermodynamics. In their simplest forms Laws of Thermodynamics can be stated as follows:

1. 1^st Law of Thermodynamics: Energy can be neither created nor destroyed.
2. 2^nd Law of Thermodynamics: The amount of unusable energy in a closed system increases.
3. 3^rd Law of Thermodynamics: As the temperature of a substance approaches absolute zero it’s entropy of approaches zero.
4. 0^th Law of Thermodynamics: Two objects in thermal equilibrium with a third object are also in equilibrium with each other.

Note: The 0^th Law is called shuch instead of the 4^th because it is more fundamental than the 1^st law but it was discovered after the other three.

Statistical Thermodynamics works at microscopic as well as macroscopic level. It explains why the four laws of Thermodynamics work as the do as well as explaining things that Classical Thermodynamics can not.

In conclusion the principles of Thermodynamics are the best tested scientific principles known. They are also so general that they apply to everything including the universe itself. Thermodynamics is path independent so it often does not matter how one get from state “A” to state “B” which is why it applies to everything.

An Introduction to Physics

Physics is the study of matter, and energy and their interactions. Physics is more than formulas that you may not be able to make sense of. While physic is scientifically expressed by formulas, it is more than the formulas. It can take the form of practical experience. 

Whether you know it or not physics found is in sports Baseball is a prime example of physics in sports, specifically ballistics. Pool is another example of physics in sports specifically collision physics 

The two main founders of physics are Galileo Galilei and Isaac Newton. These two are the main men responsible for establishing modern physics, there were others involved but they were the main ones.

Physics is central to all other physical sciences including Astronomy, Biology, Chemistry, Cosmology and Geology.  Physics has shown us much about the structure of matter, the nature of Energy and the nature of space and time. Physics has the potential to shown us how the universe works and the nature of reality itself.
