Venus is similar to Earth in many ways, which is why it is often referred to as "Earth's twin". You can't really blame us. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies;[1] the measurement and analysis of these rates is known as gravimetry. The gravity of different planets is a function of planetary mass, radius and density. Substituting r = R+h in the gravity formula, we get. Then the attraction force There is no gravitational acceleration, in that the proper acceleration and hence four-acceleration of objects in free fall are zero.
