Frequently Asked Questions

What is the gravitational constant?

G = 6.674 × 10⁻¹¹ N·m²/kg². It is a fundamental constant of nature that describes the strength of gravity.

How does distance affect gravity?

Gravitational force decreases with the square of distance. Double the distance and the force drops to 1/4 of its original value (inverse square law).
