# Dynamics and Statics

#### Introduction

Mechanics भनेको विज्ञानको एक शाखा हो जसले forces and their effects on structure (or machine) को बारेमा अध्य्यन गर्दछ। It is study of force, deformation, motion, and the relations. Mechanics लाई (a) statics vs dynamics; (b) particle vs rigid object vs many objects (‘multi-object’); and (c) 1 vs 2 vs 3 spatial dimensions (1D, 2D and 3D) आदि तरिकाले बिभिन्न 2, 3, 3 गरि 18 संयोजनहरूमा अध्य्यन गर्न सकिन्छ।
सामान्यतया, Mechanics लाई दुई मुख्य भागहरूमा विभाजन गरि अध्य्यन गरिन्छ।
1. Dynamics
Dynamics is the branch of mechanics जसले गतिमा रहेको भौतिक बस्तुहरुको विश्लेषण गर्दछ. This means that dynamics implies change. It study about forces on a body which is at motion: causes of motion such as force, normal force, and friction force; including Newton's law of motion
2. Statics
Statics is the branch of mechanics जसले स्थिर अवस्थाको वा स्थिर गतिमा चल्ने भौतिक बस्तुहरुको विश्लेषण गर्दछ . This means that statics implies changelessness. It deals with the study of forces on a body which is at rest.
