What is the mass of the moon Fg = 1.90 x 10 20th N and the distance between them is 3.9 x 10 8th m?Use the force equation to determine the mass of an object knowing the force.?
I'm on a mission: to teach people how to make exponents when you can't make the little superscript. Do it this way: Fg = 1.90 x 10^20 N.
Newton's Universal Law of Gravitation says
Fg = G*M1*M2/r^2
where G = 6.673*10^-11 nt*m^2/kg^2, M1 is the mass of the Moon, M2 is the mass of the Earth = 5.983*10^24 kg, and r is the distance between them.
