Question

Explain the phenomenon behind free fall.

Answer 1

Explanation of free fall:

1. A free fall is simply a downward motion without any initial force or velocity.
2. Our earth has the inherent property of attracting items towards it.
3. Freefall is simply a natural phenomenon on earth for any object falling from any height without any support.
4. The basis of a free-falling object is given by Sir Isaac Newton.
5. A free-falling object falls under the influence of gravity. Therefore a body that is under the effect of gravity is in its state of free fall.
6. The value of gravitational acceleration that acts on the free-falling object is $9.8m{s}^{-2}$ in a downward direction.
7. This concept of attracting the gravitational force of the earth is established for all objects. It also applies to rising upward with an initial force and falling back again towards the ground under the influence of gravity.
