Common questions
What is the Universal Gravitation formula?
Universal Gravitation is written F = Gm₁ m₂/r². Newton's law of universal gravitation. It belongs to Mechanics, under Gravitation.
What are the units in F = Gm₁ m₂/r²?
In SI units, F is gravitational force, measured in kg·m/s²; G is gravitational constant, measured in m³/(kg·s²); m₁ is mass 1, measured in kg; m₂ is mass 2, measured in kg; r is distance, measured in m.
How is the Universal Gravitation formula derived?
Fundamental empirical law. The result is F = Gm₁ m₂/r².
