Question

What is the first law of gravity?

Answer 1

1. Newton postulated only a single gravitational law.
2. The first law of gravity states that any two objects attract each other with a force $\left(F\right)$ equal to a constant (gravitational constant $G$) multiplied by the product of the masses of two objects $(m_1,m_2)$ and divided by the square of the distance $\left(r\right)$ between them.
3. It can be written as: $F=G\frac{m_1{m}_2}{r^2}$
4. Jumping on a trampoline is an example of Newton's first law.
