For this reason it doesn't match the strict definition of a free fall. A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute. In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. This is an area of study on the relationship between force and momentum that is almost completely based on the work of Sir Issac Newton, the apple loving physicist and mathematician. To start, we're going to look at Newtonian physics. The actual free fall distance on these jumps range from 5 ft on the QUICKflight Low Mount Free Fall Device to a whopping 50 ft on the FlightLine Free Fall Device!īut what do we mean by free fall device? What is free fall? You ask and we deliver, so sit back, adjust your pocket protector, and get ready for a free falling physics lesson! Define Free Fall The tower is not on fire and is not toppling, so why are you jumping? For the thrill of course! We've developed a family of free fall devices that offer a wide range of free fall experiences - with jumps ranging from 15 ft (4.5 m) to a sweat-inducing height of 80 ft (24.5 m). Imagine standing on top of a tower with your toes to the edge getting ready to jump off.
