Category:Newton's Law of Universal Gravitation

This category contains pages concerning Newton's Law of Universal Gravitation:

Let $a$ and $b$ be particles with mass $m_a$ and $m_b$ respectively.

Then $a$ and $b$ exert a force upon each other whose magnitude and direction are given by Newton's Law of Universal Gravitation:

$\mathbf F_{a b} \propto \dfrac {m_a m_b {\mathbf r_{b a} } } {r^3}$

where:

$\mathbf F_{a b}$ is the force exerted on $b$ by the gravitational force on $a$

$\mathbf r_{b a}$ is the displacement vector from $b$ to $a$

$r$ is the distance between $a$ and $b$.
