szabadesés

Szabadesés, also known as free fall, is a state of motion where an object is falling under the sole influence of gravity, without any other forces acting upon it. This concept is fundamental in physics and is often used in various fields such as aerospace engineering, skydiving, and sports. The term originates from the Hungarian word "szabadesés," which translates to "free fall."

In a vacuum, an object in free fall experiences a constant acceleration due to gravity, which is approximately 9.8 meters per second squared on the surface of the Earth. This acceleration is independent of the mass of the object, as stated by Galileo Galilei and later confirmed by Isaac Newton's laws of motion. The path of an object in free fall is a parabola when air resistance is negligible, and a more complex curve when air resistance is significant.

Free fall is a crucial concept in understanding the motion of objects in the absence of other forces. It is also essential in the design and operation of various technologies, such as spacecraft and parachutes. In recreational activities like skydiving, free fall allows participants to experience weightlessness and the sensation of flying.

In summary, szabadesés, or free fall, is a state of motion where an object falls under the influence of gravity alone. It is a fundamental concept in physics with applications in various fields and activities.
