Universal Law of Gravitation Video Lessons

Concept

# Problem: The force due to gravity between two objects can be described using the equation Fg = GM1M2/d2. In this equation, what does d represent? A) the universal gravitational constant B) the density of the smaller object C) the distance between the two objects

###### FREE Expert Solution

Force due to gravity between two objects:

$\overline{){{\mathbf{F}}}_{{\mathbf{g}}}{\mathbf{=}}{\mathbf{G}}\frac{{\mathbf{M}}_{\mathbf{1}}{\mathbf{M}}_{\mathbf{2}}}{{\mathbf{d}}^{\mathbf{2}}}}$

Fg is the force in Newtons, M1 and M2 represent the two masses in kilograms, G represents the gravitational constant, and d is the separation in meters.
