Physics students face the double challenge of grasping both complex concepts and their mathematical descriptions, and students need to be able to understand and confidently manipulate these mathematical representations. Solving conceptual and mathematical problems is an established method in physics teaching, it reinforces theory and improves the ability to apply broad physical principles and equations to specific situations. The capability to confidently solve problems goes beyond being able to tackle exam questions; it is much more powerful than memorizing a list of facts. Analytical skills and problem-solving abilities can be applied to new situations and are useful both for solving homework problems and for applying physics in everyday life.
Mechanics is the backbone of physics. and particle mechanics is 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 (Newton's laws, Friction and circular motion) including (a) string-particle systems (b) wedge-particle systems (c) spring-particle systems. Then, we apply Newton's laws to these mechanical systems with and without friction. After mastering this fundamental topic, a students can grasp the other areas of physics more easily.
