What major reason has the capture theory been rejected as a understanding of how the earth acquired its moon?
In the middle of space, far away from any other object, two slow moving astroids get close to each other. Astroid 1, a 1000kg which feels a force from astroid 2 starts accelerating towards astroid 2 at 3m/s^2 Using
Where G = 6.67408 × 10-11 m3 kg-1 s-2, if you are asked to find the force of the astroid 2 on astroid 1, Which equation do you use?
If you knew that when the astroid had an acceleration of 2m/s^2 the two astroids were 30 m apart and could find the force on the one astroid, could you find the mass of the second astroid? don't do it, just say how.
