The laws and principles of thermodynamics govern the field of Mechanical Engineering. Whenever an engineer wants to design a motor or system they must take into account laws of energy, motion and friction that will effect how the machine works. Learn more about this field, including the basic laws and rules, and how to apply these rules to the development of machines and technologies.

Physical Laws of Motion and Energy Explained

What is motion and what is energy? These fundamental questions are difficult to answer. The first attempt to give some explanations was made through classical mechanics. Here you will find a collection of articles with everything you need to know about the physical laws of motion and energy.

A Guide to Thermodynamics

One of the most fundamental science fields that has contributed to the evolution of engines since the early 19th century, thermodynamics has seriously affected our lives. In this guide we’ll start with the basics and move on to the more complicated principles and applications.
What is Friction? Forces of Friction

What is Friction? Forces of Friction

Two surfaces in contact, no matter how much smooth they may appear to be, pose some frictional force across their surfaces. Here we try to present a comprehensive explanation regarding this phenomenon occurring every day and everywhere in our life.

The Thermodynamics of Nitrogen

The correct understanding of the thermodynamic properties of the nitrogen is essential for its safe use and the development of applications. This article presents some basic concepts on thermodynamics and applies them to the calculations of the properties of this gas.
