Title: What sort of force would be needed to push the moon out of its orbit around the Earth? Post by: psyche360 on Jun 25, 2017 What sort of force would be needed to push the moon out of its orbit around the Earth? :thinking:
Title: Re: What sort of force would be needed to push the moon out of its orbit around the Earth? Post by: bolbol on Apr 14, 2022 F=MA M=mass of moon. A=change in velocity per second. Thus, to push the moon into the earth, 1 Newton of force applied over nearly infinite time would yield nearly infinite acceleration. The right question is how much energy would be required. Express this in Newton-meters per second. V(i) = Start with orbital velocity of the moon V(f) = 0 (stop the moon, it will fall gravitationally into the Earth).
