Introduction to Mechanics-I

Mechanics is a branch of the physical sciences concerned with the state of rest or motion of bodies that are subjected to the action of forces. The study of mechanics involves many more subject areas. However, initial study is usually split into two areas; statics and dynamics. Statics is concerned with bodies that are either at rest or move with a constant speed in a fixed direction. Dynamics deals with the accelerated motion of bodies. Statics can therefore be considered as a special case of dynamics where the acceleration is zero. In engineering, since many objects are designed with the intention that they are at rest or their motion remains constant, statics deserves special treatment.

Full course of Mechanics is comprised of Mechanics-I & Mechanics-II. Mechanics-I & Mechanics-II is taught in 1st & 2nd semester of BS Physics. In this semester I shall teach you historical background of Mechanics, motion of objection in straight line, vectors. Then I'll discuss motion of objects in 3D, motion under the effect of forces eg. frictional forces, normal forces and gravitational forces etc.At last of this semester I'll teach you Kinetic energy and work, potential energy and conservation of energy.We'll solve many problems to understand each of topic above.
