What is the force of gravity in Newtons? G represents the gravitational constant, which has a value of 6.674⋅10−11N(m/kg)2 6.674 ⋅ 10 − 11 N (m/kg) 2 . Because of the magnitude of G , gravitational force is very small unless large masses are involved. Is gravity a pushing force? In general relativity, gravity neither […]
