    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.

  2. 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.

  3. 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: Free-falling objects do not encounter air resistance.

  4. 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.

  5. Feb 16, 2023 · Free Fall. An object that is moving under only the influence of gravity is in free fall. In order for an object to be in free fall, wind and air resistance must be ignored. On Earth, all objects in free fall accelerate downward at the rate of gravity or 9.81\text { m/s}^2 9.81 m/s2.

  6. Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity. Is gravitational acceleration really constant? For example, when a ball is thrown up in the air, the ball's velocity is initially upward.

  7. 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.
