Timeline/Sequence — History of Kinematics Concepts — Notes

Year	Person / Event	Contribution
~350 BCE	Aristotle	Proposed heavier objects fall faster (incorrect but influential for 2000 years)
1586	Simon Stevin	Experimentally showed balls of different mass fall at same rate
1604–1608	Galileo Galilei	Established free fall under uniform acceleration; derived $s \propto t^2$ ; invented kinematic analysis
1632	Galileo	Described projectile motion as compound of horizontal uniform + vertical accelerated motion
1687	Isaac Newton	Formalised kinematics within Principia; introduced calculus to describe instantaneous rates
1736	Leonhard Euler	Formalised vector algebra; resolved forces and velocities into components
1788	Joseph-Louis Lagrange	Lagrangian mechanics — generalised coordinates extend kinematics to complex systems
1905	Albert Einstein	Special relativity modified kinematics at speeds near c; time dilation, length contraction
Present	NEET Syllabus	Classical kinematics (Galileo/Newton framework) — valid for $v \ll c$ , sufficient for all NEET problems
