![]() ![]() If a person were shaped like a cylinder, their maximum speed would be about 350 miles per hour. This is found, however, by estimating the wind resistance against a flat body. A human's terminal velocity (the fastest speed at which we may fall) is roughly 120 mph. Your average terminal velocity is at 120 miles per hour, but you may reach 200 miles per hour. But it took several minutes for its speed to decrease due to air resistance. The fastest man-made object, the space shuttle, was capable of reaching 771 km/h (465 mph). This allows them to ignore the effects of gravity and stay conscious long enough to avoid injury. They do this by focusing on objects that are fixed rather than moving, such as buildings or towers. Many high-performance skydivers are trained to control their descent using only their minds. Some people may even black out for a few seconds if their blood pressure drops too low. The heart rates of female subjects increased between 10 and 20 beats per minute over the same period.Īt 9 g's, most people experience symptoms such as dizziness, pain in their joints, and problems with vision. The average adult male heart rate increases from about 60 to 100 beats per minute during a full-body cast simulation test at 4 g's (the equivalent of Earth's gravity). A human body can be damaged by impact speeds as low as 100 km/h (60 mph). What’s the maximum speed something can fall?īased on wind resistance, a skydiver's terminal speed in a belly-to-earth (i.e., face down) free fall position is around 195 km/h (120 mph 54 m/s). This is most obvious when someone falls from a great height they often face straight up toward the sky while falling, which increases their distance through air resistance. In fact, the body would only move as far as its terminal velocity in this position!īodies also orient themselves so that they fall faster. For example, if one were standing with his or her head thrown back, eyes closed, and arms outstretched, then the body would fall more slowly because of its reduced weighting and increased surface area. At this rate, it would travel approximately 20 meters (66 feet).īut bodies fall at different rates depending on their weight and position. A body falling from a height of 10 m (33 ft) will reach terminal velocity in 5 seconds. The average adult male body weighs about 60 kg (130 lb), and the average female body weighs about 50 kg (110 lb). But since all bodies are a little bit off level, they slow down to terminal velocities between 1% and 2% of their initial velocity. The final velocity of the human body in a stable, belly-to-earth posture is around 200 km/h (about 120 mph). A human body's speed in free fall is determined by two factors: body weight and body orientation. ![]()
