Question

explain the universal law of gravity and its calculated from as well as the value of g.​

Answer 1

$\huge\purple{\mid{\fbox{Answer}}\mid}$

g is the local acceleration due to gravity between 2 objects. The unit for g is m/s^2 an acceleration. ... You get this value from the Law of Universal Gravitation. Force = m*a = G(M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth.
