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.
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.
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.
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 formula for free fall: Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as:
Sep 12, 2022 · Learning Objectives. 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.
