‘ Freeflying’ is when you use your body and the wind to hold your body in head-up and head-down orientations, and has a medium speed of around 160mph (+/- 260kph). Although freefall speed is a little bit different for everybody, having a number in your brain with which to make comparisons is important and 120mph is an approximate medium speed for the belly-down orientation used for skydiving either solo or tandem (the method for a first-time skydiver).īut there are other, more advanced ways to fall through the air that involve greater speed. This is both accurate and not really very accurate. The most common number associated with skydiving speed is 120mph (200kph). Different Methods Of Skydiving Produce Different Speeds Again, very basically, if you want to go forward, you angle your body to push air away behind you. The best way to feel this on the ground is by sticking your hand out of a car window as the car is moving and paying attention to what happens when the air hits you at various angles. As you fall through the air the wind resistance amounts to a physical force that can be manipulated to move you in different directions. In skydiving, you can also use drag to control how you move around in the sky. Very basically, if you make yourself smaller, you go faster because of less drag. Managing drag allows skydivers to control their speed, meaning they can match their fall rates. While you cannot change your weight in freefall, you can change your shape and therefore how much drag you create. It is possible for a skydiver to control their terminal velocity. The Freefall Skills of a Skydiver Can Change Terminal Velocity The combined effect of these forces is what determines the terminal velocity of an object. At the same time, the shape of an object and how big it is causes drag as it travels through the air, thus causing it to slow down again. The overall mass of an object-how big and how heavy it is-is what causes it to speed up. Gravity is a constant force generated by our planet, and if our falling objects were all exactly the same size, they would indeed fall at the same speed. The (Brief) Science of Objects in Freefall So, how do terminal velocity, acceleration, wind speed, jump angles, and all of the other fascinating physical factors work while skydiving? Let’s have a look. The scientific word for the maximum speed an object can achieve while falling is ‘ terminal velocity’, but this speed is not the same for different objects (like people). But how fast? This is a good question as the answer involves a bit about how skydiving works. It is very likely that your brain understands when you freefall from an airplane, you will go fast.
