Question

what is free fall explain briefly​

Answer 1

Answer:

In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. ... A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement.

Answer 2

$\huge\bf{Answer :}$

✥The act of falling of a body ( or an object ) from an altitude towards the earth's surface under the influence of gravitational force of the Earth ( excluding all extra forces which are acting on it ) is called Free Fall.

⇒ Such a body which is experiencing free fall is referred as "Freely Falling Body".

⇒ If a body falls towards the earth's surface on it's own ( without the influence of any other force ) , we say that the object is under free fall or it is freely falling body.

⇒ Earth has the potential to attract all the bodies which lies near it's surface , when a body ( such as ball ) is dropped from the roof , it's falls towards the earth's surface.

⇒ The acceleration which is produced in the freely falling bodies is same for all the respective bodies and it is not dependent on the mass of the falling body.

⇒ Galileo Galilei was the scientist who conducted several experiments on the freely falling body.

⇒ Robert Boyle was the scientist who proved that a feather and a coin can be dropped at the same rate when no air resistance is present.
