Gravitational force describes the interaction of one object with mass with another object with mass.

- a model used to explain the influence that an object extends into the space around itself, producing a force on another object. This force is always attractive.
Equation: Fg = mg, where Fgis the Force of Gravity in Newtons, m is mass in kilograms, and g is the acceleration due to gravity in m/s/s
- every particle attracts every other particle in the universe 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.
Equation: Fg = Gm1m2/r^2, where Fg is the Force of Gravity in Newtons, G is the gravitational constant 6.7 x 10^-11 N*m^2/kg^2, m is mass in kilograms, and r is the radius in meters
