Mechanics is the foundational branch of physics that deals with the study of motion, forces, energy, and the behavior of matter under different conditions. This course introduces the principles governing the physical world, beginning with measurement and units and gradually progressing through kinematics, dynamics, work and energy, gravitation, rigid body motion, relativity, fluid mechanics, and elasticity.

Students will gain a clear understanding of:
The importance of precise measurement and dimensional analysis.
Motion in one, two, and three dimensions, including projectile motion.
Newton’s laws of motion, friction, and circular dynamics.
Work, energy, power, and conservation principles.
Gravitational laws, orbital mechanics, and satellite motion.
Rigid body dynamics, torque, angular momentum, and moment of inertia.
Special theory of relativity and its consequences.
Fluid mechanics concepts such as Bernoulli’s principle, viscosity, and surface tension.
Elasticity, stress‑strain relationships, and elastic moduli.

By the end of this course, learners will develop strong analytical skills, mathematical reasoning, and the ability to apply physical laws to real‑world problems. This series builds the essential foundation for advanced studies in physics and engineering, ensuring conceptual clarity and practical insight into the mechanics of the universe.
