Meaning of Free Fall
What is Free Fall:
Free fall is called any vertical fall without support of any kind, whose path is subject, hardly, to the force of gravity. It is a concept applied to physics, but it is also a sports practice.
Free fall in Physics
According to Physics, a free fall is designated as the one that a body experiences when it is only subjected to the action of gravity, and that involves a vertical descent. Hence, this definition excludes falls influenced, to a greater or lesser extent, by air resistance, as well as any other that occurs as a result of the presence of a fluid.
In a vacuum, the acceleration is constant, and it is the same for all bodies, regardless of their shape and weight. The presence of fluids, such as air, for example, tends to slow down this movement, making the acceleration depend on other factors, such as the shape, weight or density of the body.
The acceleration in free fall is the acceleration of gravity, which is approximately 9.81 m / s2. If the movement is downward, the acceleration value is positive, while if it is a vertical ascent, this value becomes negative, since it constitutes a decelerated movement.
The vertical ascent is called vertical throw, and it refers to the movement in which an object is thrown in a straight line upwards.
Free fall in sports
A form of parachute jump is known as free fall, which consists of jumping from an aircraft in flight and delaying the opening of the parachute during descent to the ground, so that a considerable part of the journey is made without any kind of lift. In this sense, it is an extreme sport, as it is highly risky.
