The Physics of Skydiving, Waialua, Hawaii

If you’ve always wanted to learn to skydive, you’ve likely daydreamed about what it feels like to experience that adrenaline rush. But have you ever stopped to consider the scientific concepts that make skydiving possible? Find out what you need to know in this guide to the physics of skydiving.

What Forces Make Skydiving Possible?

Waialua skydivingSkydiving works because of the relationship between gravity and air resistance. When a skydiver jumps from an aircraft, they gain both speed and air resistance as they free fall. The amount of air resistance increases until it equals the force of gravity, at which point the skydiver reaches terminal velocity. Their descent maintains a constant speed rather than accelerating. The skydiver’s speed decreases after they open their parachute, then a new terminal velocity is reached when air resistance and gravity balance again.

What Affects Air Resistance?

The amount of air resistance on a skydiver depends largely on the cross-sectional area of the skydiver’s body. Someone who skydives feet first, head first, or in a tucked position experiences less air resistance than a skydiver who falls in a spread-eagle position. When the parachute opens, it creates a larger cross-sectional area and increases the air resistance, causing the skydiver’s speed to decrease.
