Newton's Law of Universal Gravity

Written by Jerry Ratzlaff on . Posted in Properties

All objects in the universe exert a gravitational force of attraction on each other.

  • Abbreviated as g (gravity)

formula

\(F = G \frac {m_1 m_2} {r^2} \)

Where:

\(F \) = gravitational force

\(G\) = universal gravitational constant  

\(m_1\) = mass

\(m_2\) = mass

\(r\) = distance between objects

Solve for:

\(m_1 = \frac {F   r^2} {G m_2} \)

\(m_2 = \frac {F   r^2} {G m_1} \)

\(r = \sqrt { \frac {G m_1 m_2} {F} } \)
