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 quantum theory, and see related topics such as action and motion.
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.
Free fall can mean a fast fall from a great height under gravity, or a sudden loss of value or popularity. Learn more about the physics and business meanings of free fall, and see examples from the Cambridge English Corpus.
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:
Free fall is the condition of unrestrained motion in a gravitational field, or such motion. It can also mean a rapid and continuing drop or decline, as in stock prices. See more meanings, examples, and word history of free fall.
Free fall can mean a fast fall from a great height under gravity, or a sudden loss of value or popularity. Learn more about the physics and business meanings of free fall, and see examples from various sources.
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.
