Why is the gravitational constant important?
Why is the gravitational constant important? The constant, G, determines the strength of Newton’s inverse square law in a particular system of physical units and is, not surprisingly, known as Newton’s constant of gravitation. It is considered to be a fundamental constant of nature. Gravity is also by far the weakest force. Who found the […]
Has anyone hit a homerun in every ballpark?
