Free Fall Equation For Distance. The formula for the time of free fall is: 5gt 2 v gt v key:
H = ½ × g t 2, the value of distance travelled by a free falling object can be calculated. In the event that you have the fall distance of an object but don’t have the fall time, you can. The fall clearance needed for this system is:
H is the height of the free fall;
Free fall (distance and velocity) Pea extension = 0,8 meter (2,5 ft) harness stretch = 0,3 meter (1 ft) (or more, depending on the manufacturer) safety factor = 0,6 meter (2 ft) a fall clearance of 3,7 meters (12,1 ft) is required when this fall protection system is used. At t = 8 s. If you know the height from which the object is falling, but don't know the time of fall, you can use this calculator to find it, too!
