# Thermodynamics

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.

### Heat Resistant Materials for Home and Industrial Applications

Materials that have the ability to protect equipment and instruments from being damaged due to high temperature are called heat resistant materials. These materials can be found on the inside of ovens, in car parts, on the manufacturing floor of industrial buildings, etc.

### Calculating Moment of Inertia Using Routh's Rule and Through the Method of Integration

Using Routhâ€™s rule and the integration method, we can evaluate the moment of inertia of a body having mass and area. We can further implement methods for finding the moment of inertia for rods and flat surfaces.

### 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.

### Explanation of How to Solve Inelastic Collision Problems

The article describes in detail the steps on how to solve inelastic collision problems by using the momentum and energy conservation principles.

### Explanation of How to Solve Elastic Collision Theory Problems

The article describes in detail the steps on how to solve elastic collision problems by using the momentum and kinetic energy conservation principles.

### Momentum - Theory of Conservation of Momentum - Elastic & Inelastic Collisions

What is momentum and what is the definition of the conservation law of momentum? What are their meanings? Learn about the role of momentum in the case of elastic and inelastic collisions.

### 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.

### The Close Connection Between Classical Thermodynamics and Relativity Explained

Classical thermodynamics can be combined with relativity in order to accurately predict changes in mass and energy; before and after a thermodynamic process has taken place.
