Hint: Free fall is defined in Newtonian physics as any motion of a body in which gravity is the only force acting on it. A body in free fall has no force acting on it in general relativity, where gravity is reduced to a space-time curvature.
Complete step by step solution:
A free fall is simply a downward motion with no force or velocity applied at the start. Our planet has the natural ability to attract things to it. As a result, a free fall for any object at any height without any support is simply a natural phenomenon on Earth. Consider a free-falling apple from a tree or the ball falling from our hands when we toss it upside down. The foundation of a free-falling object is provided by Sir Isaac Newton.
A free-falling object is subject to gravity's pull. As a result, a body in free fall is one that is under the influence of gravity. It does not require any force, and it is unaffected by air resistance. The gravitational force has an effect on the free falling object because of the gravitational acceleration. In the downward direction, it has a value of\[9.8\text{ }m/{{s}^{2}}\].This concept of attracting the gravitational force of the earth is established for all objects in the air.
This concept does not have to be applied to a falling downward object; it can also be applied to a rising upward object under the gravity influence of\[9.8\text{ }m/{{s}^{2}}\]. Let's look at the concept of free fall objects, their speed and velocity, and motion equations for free fall objects.
Note:
The term "free fall" is frequently used in a broader sense than that defined above. Free fall is the term used to describe falling through the atmosphere without the use of a parachute or other lifting device. Because aerodynamic drag forces prevent full weightlessness in such situations, a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.
