True Mass
True Mass
is it true that every element with mass has a gravitational force ?
is this true
if so does that mean that even my book has a gravitational field and it can even attract things of lower mass and gravitational force ???
and what is the mathematical relation between the both (mass and gravitational force ) ??
and how r they both related with each other ??
Yes it's true. In fact, all energy and matter exerts gravitational force (even light).
Your book has a gravitational field but it's very small compared to the earth and much smaller than other forces that would keep other objects from "falling" to your book.
In terms of exerting actual force, because every action has an equal and opposite reaction, each object the earth pulls on, pulls on the earth with the same force. If the earth is pulling on you with 1000N, you are pulling on the earth with 1000N as well. But because the earth is so big, your pull amounts to nothing.
F_g = G*m1*m2/d^2
The above equation relates gravitational force between two masses. If you plugged in Earth's mass and radius and divide out the other mass, you would get 9.8m/s^2, earth's gravitational acceleration.
G is a very small number (~10^-12 for SI units), which makes sense since you want a manageable force despite the whole earth pulling on you.
