fremfall

Fremfall, also known as free fall, is a state of falling under the influence of gravity alone, without any other forces acting upon the falling object. It is a fundamental concept in physics and is often used in various fields such as aerospace engineering, skydiving, and sports. The term "fremfall" is derived from the German word "freier Fall," which translates to "free fall" in English.

In a free fall, the only force acting on an object is gravity, which causes it to accelerate towards the center of the Earth. The acceleration due to gravity is approximately 9.8 meters per second squared (m/s²) at sea level. This means that an object in free fall will increase its speed by 9.8 m/s every second it falls.

Free fall is a crucial concept in understanding the motion of objects in the absence of other forces, such as air resistance. It is also essential in the design and operation of various technologies, including aircraft, spacecraft, and parachutes. In skydiving, for example, free fall is the state in which a skydiver falls from a certain height before deploying a parachute to slow down.

In summary, fremfall, or free fall, is a state of falling under the influence of gravity alone, without any other forces acting upon the falling object. It is a fundamental concept in physics and has numerous applications in various fields.
