Enter the total time of free fall (s) into the Free Fall Distance Calculator. The calculator will evaluate and display the Free Fall Distance. 

Free Fall Distance Formula

The following formula is used to calculate the Free Fall Distance. 

FFD = .5*g*t^2
  • Where FFD is the Free Fall Distance (m)
  • t is the total time of free fall (s) 
  • g is the acceleration due to gravity (9.81 m/s^2)

To calculate a free fall distance, square the free fall time, multiply by the acceleration due to gravity, then divide by 2.

How to Calculate Free Fall Distance?

The following example problems outline how to calculate Free Fall Distance.

Example Problem #1:

  1. First, determine the total time of free fall (s).
    • The total time of free fall (s) is given as: 50.
  2. Finally, calculate the Free Fall Distance using the equation above: 

FFD = .5*g*t^2

The values given above are inserted into the equation below and the solution is calculated:

FFD = .5*9.81*50^2 = 12262.5 (m)

Example Problem #2: 

For this problem, the variables needed are provided below:

total time of free fall (s) = 45

${V2} = ${number 4}

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

FFD = .5*g*t^2 = ?
