Mechanics is the backbone of physics, and particle mechanics is the most fundamental aspect. It has two parts; kinematics and dynamics; we begin with the units and dimensions as the first chapter and treat the 2nd chapter (vectors) as a specific chapter to deal with all vector operations (addition, subtraction and multiplication). The kinematics is dealt with in another three chapters (general kinematics with basic definitions of velocity, acceleration etc., 1-D and 2-D); 1-D deals with free fall and graphical solution; 2-D deals with projectile motion, relative motion, circular motion. Then, in dynamics we have three chapters (Newtons laws, Friction and circular motion) including (a) string-particle systems (b) wedge-particle systems (c) spring-particle systems. Then, we apply Newtons laws to these mechanical systems with and without friction.
