𝗠𝗼𝘁𝗶𝗼𝗻 𝗨𝗻𝗱𝗲𝗿 𝗚𝗿𝗮𝘃𝗶𝘁𝘆 𝗔𝗻𝗱 𝗘𝗾𝘂𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗠𝗼𝘁𝗶𝗼𝗻:

When a body is throw vertically upward or it is dropped from certain height it will undergo Motion Under Gravity.

𝗗𝘂𝗿𝗶𝗻𝗴 𝗠𝗼𝘁𝗶𝗼𝗻 𝗨𝗻𝗱𝗲𝗿 𝗚𝗿𝗮𝘃𝗶𝘁𝘆 𝗯𝗼𝗱𝘆 𝗺𝗼𝘃𝗲𝘀 𝘄𝗶𝘁𝗵 𝗰𝗼𝗻𝘀𝘁𝗮𝗻𝘁 𝗔𝗰𝗰𝗲𝗹𝗲𝗿𝗮𝘁𝗶𝗼𝗻 𝗰𝗮𝗹𝗹𝗲𝗱 𝗚𝗿𝗮𝘃𝗶𝘁𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗰𝗰𝗲𝗹𝗲𝗿𝗮𝘁𝗶𝗼𝗻.

Denoted by g, and it's value is 9.8m/s²

This value is g near the surface of the Earth/where the Gravitational Field is Exert.

* The Direction of gravitational Acceleration is always towards the center of Earth.

𝗕𝗮𝘀𝗶𝗰 𝗣𝗼𝗶𝗻𝘁𝘀:

When an Object is dropped from certain height, it initial Velocity is zero.
vi= 0

When an Object is throw upward, its final Velocity will be zero
vf=0

There are three Equation of Motion:
1) vf= vi + at
2) S = vit + 1/2 at²
3) 2as = Vf² - Vi²

These Equtaions of Motion only applicable when the body moves with uniform Acceleration.

Equation of Motion will be after Acceleration is taken as Gravitational Acceleration :

1) vf = vi + gt
2) S = vit + 1/2 gt²
3) 2gs = vf² - vi²

Here,
vf = final Velocity
vi = inital Velocity
a = Acceleration
g = Gravitational Acceleration
S = Distance
