Important Points
🔹Newton's First Law: Defines inertia and resistance to motion.
🔹Newton's Second Law: Relates force, mass, and acceleration (F = ma).
🔹Newton's Third Law: Explains action-reaction force pairs.
🔹Friction: The resistive force opposing motion.
🔹Free-Body Diagrams: Essential for force analysis in problems.
Important Formulas
☑️F = ma – Newton’s Second Law
☑️P = F · v – Power in terms of force & velocity
☑️f = μN – Frictional Force
☑️W = mg – Weight of an object
☑️a = (v_f - v_i) / t – Acceleration formula
