KEY ICONS TO LOOK FOR: for torque is force times distance . The hands are far away from the skydiver’s center of mass, so distance is maximized. Therefore, even a small force, such as a hand movement, can create a significant amount of torque to turn the skydiver in different directions. Wingsuits If regular skydiving isn’t extreme enough for you, check out the even more extreme sport of wingsuit flying. The jumper uses a special suit called a wingsuit, also sometimes called a birdman suit or squirrel suit. The jumpsuit has arm and leg wings made Skydivers also turn in midair. How? It requires torque and rotational velocity, or speed. Skydivers can turn their hands to produce a force that creates rotation. If a skydiver moves their hands to push air left, the body rotates to the right. The formula

of inflatable cells that increase the skydiver’s surface area to increase lift. The suit allows wingsuit flyers to travel incredible horizontal distances at speeds of 220 miles per hour. That’s fast! Jumpers also have a much slower descent—sometimes as much as 80 percent slower than a egular skydiver. These athletes train for years to achieve maximum performance while wearing the suit. Wingsuit flying is much more complex than regular skydiving, and it carries greater risk of uncontrollable spinning.
