Summary of Lecture 1:
The course on Classical Mechanics will cover basic Newtonian mechanics, equations of motion, work-energy relations, motion under resistive medium, moving coordinate systems, central orbit wicked dynamics, and Lagrangian dynamics.

Key Concepts
- The fundamental equation of Newtonian mechanics is F = ma, valid for systems with constant mass.
- Work done in a conservative force field leads to the conservation of total mechanical energy.
- An inertial frame is defined as a frame of reference where the equation of motion of a particle remains invariant.
- Different types of forces are discussed, including constant force, force dependent on time, central force, and viscous drag force.
Notable Quotes
— 21:53 — « If the velocity is not a constant, then we will have an additional term, which is V dot. »
— 23:44 — « An inertial frame is a frame which is either at rest or moving with a constant velocity with respect to a fixed frame. »
— 27:41 — « Viscous drag force is proportional to the velocity of the object, like throwing a chalk in the air in a room. »
