freefall, in mechanics, state of a body that moves freely in any manner in the presence of gravity. The planets, for example, are in free fall in the gravitational field of the Sun.

In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
12 wrz 2022 · An interesting application of Equation 3.3.2 through Equation 3.5.22 is called free fall, which describes the motion of an object falling in a gravitational field, such as near the surface of Earth or other celestial objects of planetary size.
A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important motion characteristics that are true of free-falling objects:
The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work. When this happens, an object may be falling, but it is not in free fall. Free fall occurs whenever an object is acted upon by gravity alone. Try this experiment.
28 sty 2024 · For the ideal situations of these first few chapters, an object falling without air resistance or friction is defined to be in free fall. The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called acceleration due to gravity.
22 gru 2020 · Free fall refers to situations in physics where the only force acting on an object is gravity. The simplest examples occur when objects fall from a given height above the surface of the Earth straight downward – a one-dimensional problem.
