## Frequently Asked Questions

How do you calculate free fall?

How to use the free fall calculator: an example Determine the gravitational acceleration. Choose how long the object is falling. Calculate the final free fall speed (just before hitting the ground) with the formula v = g*t = 9.80665 * 8 = 78.45 m/s.

How to calculate free fall?

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.

How do you calculate free fall distance?

Calculate the final free fall speed (just before hitting the ground) with the formula v = g*t = 9.80665 * 8 = 78.45 m/s. Find the distance traveled by the falling object, using the equation s = 0.5 * g * t^2 = 0.5 * 9.80665 * 8^2 = 313.8 m.

What is the equation for free fall velocity?

The equation to calculate a free-falling object's velocity or time spent falling is velocity equals gravitational acceleration multiplied by time. This occurs if three conditions are given: an initial velocity of zero, a hypothetical infinite space to fall in and negligible air resistance. Take for example an object falls for 120 seconds.
