Which famous scientist is known for his laws of motion and universal gravitation? A) Albert Einstein B) Isaac Newton C) Galileo Galilei D) James Clerk Maxwell
VerifiedAnswer: B) Isaac Newton
Explanation:
Isaac Newton is the brilliant scientist who gave us the fundamental laws that explain how objects move and what keeps us grounded on Earth. Born in 1642, Newton revolutionized our understanding of physics and laid the foundation for classical mechanics that we still use today.
Newton's three laws of motion are cornerstones of physics. The first law states that an object at rest stays at rest, and an object in motion continues moving at constant velocity unless acted upon by an external force. The second law gives us the famous equation F = ma, relating force, mass, and acceleration. The third law tells us that for every action, there's an equal and opposite reaction.
His law of universal gravitation explains why apples fall from trees and why planets orbit the sun. This law states that every particle in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. This single principle explains everything from ocean tides to planetary motion.
While the other scientists mentioned made significant contributions, they're known for different discoveries. Einstein developed the theory of relativity, Galileo pioneered astronomical observations and early motion studies, and Maxwell formulated the theory of electromagnetic radiation. However, Newton specifically established the mathematical framework for motion and gravity that bears his name.
