In different situations idealization is important to understand the various conditions. Idealization is the process of acquiring the knowledge by using the hypothetical model and these models is significant to know the actual problems in real life. It means the main motto of making model is to understand the reasonable correlation with the fact. Computational explanation can easily enhance the knowledge of people because models are important to solve out the actual problems. The physical sciences are imagined in a proper way through models and computations are done with proper ingenuity, insight, and imagination properly through real life condition.

**What are the various fundamentals of idealization of mechanics?**

**Particle –**

A particle is the substance which does not have any size, but its mass is concentrated at a articular point. If you go through the mathematical term, then it describes that how a point object whose mass is considered as the point mass and whose dimension approaches to zero. It is well known that a particle is completely a point when it needs to be shown. It is an important part of idealization and you cannot neglect this point mass while the idealization needs a proper solution through models.

**Rigid body –**

When the relative movement of the particles in a body is considered as zero or completely negligible, then it is known as a rigid body. Deformation to a certain degree is always there during the action of forces. However, in some cases it is completely negligible. Computations are simplified on the basis of this concept of the rigid body.
