Newton's Laws of Motion
Three laws that govern all motion on Earth and in space; the foundation of classical mechanics
England ๐ฌ๐ง 1687 Physics
Key Facts
- 1
1st Law (Inertia): a body at rest stays at rest unless acted upon by a net external force
- 2
2nd Law: F = ma โ force equals mass times acceleration; explains how rockets, cars and falling objects move
- 3
3rd Law: every action has an equal and opposite reaction โ explains thrust, swimming, and recoil
๐ฌ Did you know? Newton reportedly discovered gravity after seeing an apple fall โ though the moon, not the apple, was the key insight that led to the inverse-square law
