Key Concepts

Newton's Law of Universal Gravitation

Newton's law of universal gravitation states that every two objects with mass attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This formula provides the foundation for calculating gravitational forces in various contexts.

Gravitational Constant (G)

The gravitational constant is a fundamental constant in physics that quantifies the strength of the gravitational force between two masses. It is a key part of the gravitational force equation and has a value of approximately 6.67×10?¹¹ N·m²/kg², serving as the proportionality factor in Newton's law of universal gravitation.

Inverse Square Law

The inverse square law describes how the strength of the gravitational force diminishes with distance. Specifically, as the distance between two masses increases, the gravitational force decreases proportionally to the square of that distance, which is a critical concept in understanding gravitational interactions.
