Question

Heya mates

What do you mean by term free fall ​

Answer 1

$\huge\bf\purple{Hello!!!!}$

In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute. A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement. For this reason it doesn’t match the strict definition of a free fall.

✍️The term "" FREE FALL "" describes that any body or mass is falling due to the acceleration due to gravity.

✍️ It is generally related to the Kinematics part of physics.

✍️ The body which is falling freely is not affected due to air resistance or friction due to anything.

✍️ It is only the affect of gravity which is considered in these motions.

✍️ This type of motions follow Straight line or rectilinear motion.

✍️ On earth, the acceleration due to gravity in case of free fall is 9.8 m${s}^{-2}$.

✍️ Examples of free fall are :-

=> An apple falling from tree.

=> Throwing a ball and catching it.

=> Dropping a coin from a height.
