Free fall is the state of a body that moves freely in any manner in the presence of gravity. Learn how free fall applies to planets, spacecraft, tides, and more from Britannica's editors.
- The Editors of Encyclopaedia Britannica
In Newtonian physics, 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.

Sep 12, 2022 · Use the kinematic equations with the variables y and g to analyze free-fall motion. Describe how the values of the position, velocity, and acceleration change during a free fall. Solve for the position, velocity, and acceleration as functions of time when an object is in a free fall.
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:
Learn about the factors that affect the acceleration due to gravity and how to perform experiments to test them. Explore the history of Galileo's discovery of the free fall and his method of scientific observation.
Learn what free fall is, how to use the kinematic equations with g, and how to solve problems involving vertical motion. See examples of free fall with different initial velocities and positions.
