How do you find free fall acceleration of a planet? Estimate the total mass of the planet in kilograms. Estimate the radius of the planet, from its center to its surface, in meters. Divide the total mass by radius squared. Multiply the result by the universal Gravitational constant, 6.67×10 -11 N·m 2 ·kg -2. The result is the gravitational force of the planet, which is also its free fall acceleration.
