Answer 2

Free fall :-

✨Definition :- A body falling towards the center of the earth under the influence of a single force only, which is the gravitational pull of the earth, is said to be a free fall. In physics Free fall is a motion of a body where gravity is the only force acting on it.

$Free \: fall \: : g = - 9.8m \: sec$

✨Examples :-

1. Falling an object from the top.

2. The stones and a feather falling in vacuum.

The acceleration of the body is equal to the acceleration due to gravity.

So, The value of a will be g.

a = g

The equation of motion for free fall :-

$1. \: v = u + gt$

$2. \: h = ut + \frac{1}{2} {gt}^{2}$

$3. \: {v}^{2} - {u}^{2} = 2gh$
