Question

What is the formula for Newton's law of universal gravitation?

Answer 1

Newton's law of universal gravitation.

Newton's Law of Universal Gravitation says that each and every particle in the universe attracts every other particle inside the universe with a force that is exactly proportional to the product of their masses and inversely proportional to the square of the distance between them.

$$\begin{gathered} F\propto \frac{m_1{m}_2}{r^2} \\ F=G\frac{m_1{m}_2}{r^2} \end{gathered}$$

Where,

• F is the gravitational force.
• m₁ and m₂ are the mass.
• r is the distance.
• G is the universal gravitational constant ($6.673\times {10}^{-11}\frac{N{m}^2}{k{g}^2}$)

Hence, the formula for Newton's law of universal gravitation is $\mathrm{F}=\mathrm{G}\frac{{\mathrm{m}}_1{\mathrm{m}}_2}{{\mathrm{r}}^2}$.
