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.
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 mechanics, and see related topics such as action and equivalence principle.

Sep 12, 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.
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.

- *note: the _ symbol refers to a subscript. So, v_f refers to the final velocity. Sorry, but I believe the acceleration is -5m/(s^2). x_f = x_i + v_...

- If you dont mind me answering, we know that acceleration due to gravity is positive or negative when the question we are doing tells us that either...
- Rearranging equations is part of algebra. There are also lots of videos on Youtube. Basically, if 1+2=3 then, 2=3-1. So if the equation is v=v0+at...
