Warm-Up: Prerequisite Review

These questions review concepts needed for this section.

Newton's Law of Gravitation is $F = \frac{Gm_1 m_2}{r^2}$ . Which term in this formula plays the same role as the charges in Coulomb's Law?

The constant $G$

The distance $r$

The masses $m_1$ and $m_2$

The force $F$
