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.

Learn the key terms and skills for acceleration due to gravity and freefall motion, with examples and exercises. See common mistakes and misconceptions, and join the conversation with other learners.
- *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_...
- CONSTANT VELOCITY =>If you say that velocity is constant, is just a way to say that the velocity does not change with time...;) TERMINAL VELOCITY =...
- 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...
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 the concept of free fall, a situation where the only force acting on an object is gravity and hence acceleration due to gravity. Find the formula for free fall and see how to solve problems with examples.
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.
Learn what is free fall, how to calculate the acceleration due to gravity and how to use equations of motion during free fall. Watch a video and test your knowledge on free fall with MCQs.
