1. The problem statement, all variables and given/known data find the speed of a satillite in orbit 1000km above the earths surface. mass of earth 5.98*10^24kg mass of satellite = 50.0kg radius of earth=6.38*10^6m 2. Relevant equations so i used V= square root of G*mass of earth/r 3. The attempt at a solution V= square root of (6.673*10^-11)(5.98*10^24)/7.38*10^6) note***7.38*10^6 is the radius of the earth plus the 1000km above the earths surface*** i get V= 7.353*10^3m/s ok now my real question is if i DECREASE the distance above the earth lets say by 100km i know that the velocity or my speed will increase but can someone tell me why this increases? i understand how in figuring out with numbers but why does the speed increase as the distance gets closer to the center?
