💡 Newton's Law of Universal Gravitation
F = Gm₁m₂/r² — Every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

Understanding Universal Gravitation
Newton's law of universal gravitation states that every particle attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The Gravitational Constant
G = 6.674 × 10⁻¹¹ N⋅m²/kg² — This tiny constant explains why we only notice gravity from extremely massive objects like planets and stars.
Applications
- Orbital mechanics: Predicting satellite and planet orbits
- Space missions: Calculating trajectories and fuel requirements
- Tides: Moon and Sun's gravitational pull on Earth's oceans
