自由落体速度 人的自由落体速度

It is a common misconception that with sufficient training, one can jump from great heights, perform several acrobatic maneuvers in mid-air, and land safely. From a scientific standpoint, this is impossible as it requires the ability to nullify the gravitational potential energy.

While it may be theoretically possible to perform flips and rolls during a 100-meter free fall, this feat can only be accomplished by a superhuman.

Even if one has received training in martial arts and claims to have mastered the art of "lightness," it is strongly advised to refrain from attempting such a dangerous act. The consequences of a failed attempt can be fatal. A 100-meter drop, equivalent to approximately 34 stories, requires a different level of physical prowess than simply ascending a 20-story building.

Ignoring air resistance, the equation for free fall under Earth's gravity is: v²=2gh

where v is velocity, g is the acceleration due to gravity (9.8 m/s²), and h is the height of the fall.

Using this formula, we can calculate the velocity upon impact when falling 100 meters:

v²=2gh=√2×9.8×100m/s≈44.27m/s

A free fall from 100 meters takes approximately 4.52 seconds, resulting in a terminal velocity of 44.27 m/s (≈160 km/h). Without superhuman abilities, any acrobatic maneuvers performed during the fall will ultimately lead to a collision with the ground at a speed that can cause severe injuries or even death.

While high-dive competitions showcase athletes performing graceful and stunning maneuvers, these jumps are typically performed from 10-meter platforms - only one-tenth of the 100-meter drop. Even at this reduced height, untrained individuals attempting such jumps can face significant risks of injury.

Cliff-diving photos might give the impression of great heights, but in reality, most such jumps are well beneath 30 meters.

Before participating in competitive high-diving events, extensive preparation, safety checks, and weather monitoring are conducted. Despite these measures, accidents can still occur.

High-diving athletes, like acrobats, require dedicated training that often begins as early as age 6 with jumps from low heights. Many are eliminated at the 10-meter mark, and only a select few worldwide attempt dives exceeding 20 meters.

In water, falling from heights exceeding 20 meters without proper training poses extreme risks. On land, such jumps are even more dangerous.

Therefore, it is ill-advised to attempt high-altitude jumps inspired by fantasy films or unrealistic kung fu scenarios. Such actions can lead to serious injuries or even death.

It is important to conduct thorough research and dispel misconceptions before engaging in potentially dangerous activities. Aspiring extreme athletes should seek professional guidance and dedicate themselves to rigorous training.
