1. Intro to Physics Units

A box moving with an initial speed v is accelerated horizontally. If x is measured in [m], v in [m/s], a in [m/s²], t in [s] which of the following equations is correct for solving the distance x?

Newton's Law of Gravitation describes the attraction force between two masses. The equation is $F=G\frac{m_1{m}_2}{r^2}$ where F is in [], m₁ and m₂ are masses in [kg], and r is the distance in [m] between them.

Determine the units of the Universal Constant G.
