What is the gravitational constant on the moon? Bob A. Solution: Chapter 12 Gravity Q.19P. In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag).This is the steady gain in speed caused exclusively by the force of gravitational attraction.All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies; the measurement and analysis of these rates is known as . h In the Schwarzschild metric, free-falling objects can be in circular orbits if the orbital radius is larger than This is what allows us to use the Earth's radius for r. The value obtained agrees approximately with the measured value of g. The difference may be attributed to several factors, mentioned above under "Variations": There are significant uncertainties in the values of r and m1 as used in this calculation, and the value of G is also rather difficult to measure precisely. For other uses, see, This article is about effects of long acceleration. What is the force of Venus's gravity on the astronaut? Get a free answer to a quick problem. Similar size, mass and density. .
