Newton's law of universal gravitation
KidzSearch Safe Wikipedia for Kids.
Newton's universal law of gravitation is a physical law that describes the attraction between two objects with mass. It is talked about in Isaac Newton's Philosophiae Naturalis Principia Mathematica.^{[1]}^{[2]} The law is part of classical mechanics.
The formula is
[math]F_{g} = G \frac{m_1 m_2}{r^2},[/math]
In this equation:
- F_{g} is the total gravitational force between the two objects.
- G is the gravitational constant.
- m_{1} is the mass of the first object.
- m_{2} is the mass of the second object.
- r is the distance between the centers of the objects.
In SI units, F_{g} is measured in newtons (N), m_{1} and m_{2} in kilograms (kg), r in metres (m), and the constant G is approximately equal to Lua error in package.lua at line 80: module 'Module:Gapnum' not found..^{[3]}
