ALL objects attract each other with a force of gravitational attraction. The parameters and denote the ionization frequency and the recombination rate. The Law of Universal gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points and this force is proportional to the masses of the objects and inversely proportional to their separation This attractive force always points inward from one point to the other.
The greater the distance the stronger the gravitational force D.
I am a theatre geek. The greater the distance the weaker the gravitational force C. Lets practice solving problems using. 2 By gravitation the sun and planets act and react upon one another.
