Who extrapolated simple observations on motion of bodies on inclined planes?

Correct option is D

Correct Answer: (d) Galileo
Explanation:
· Galileo Galilei conducted experiments on inclined planes to study how bodies accelerate.
· From these observations, he concluded that bodies under gravity experience uniform acceleration, and he mathematically described motion — a major milestone in physics.
Information Booster:
· Galileo’s inclined plane experiments helped him derive:
· s∝t2 (distance ∝ square of time)
· The concept of inertia, later formalized by Newton
· He disproved Aristotle's belief that heavier objects fall faster.
· Often called the "Father of Modern Physics".
Additional Knowledge:
· (a) Aristotle:
· Ancient Greek philosopher.
· Proposed that heavier bodies fall faster — a theory later disproved.
· (b) Newton:
· Formulated the Three Laws of Motion and Law of Universal Gravitation.
· Wrote Philosophiae Naturalis Principia Mathematica (Principia).
· Developed calculus, reflecting telescope, and major optics contributions.
· (c) J.J. Thomson:
· Discovered the electron in 1897.
· Proposed the Plum Pudding Model of the atom.
· Won the 1906 Nobel Prize in Physics for his work on conduction of electricity in gases.
