❥︎ What is Acceleration due to Gravity?

$\huge\pink{\mathfrak{❥︎ᴀղsաҽɾ❄︎ :-}}$

★ Acceleration due to gravity is the acceleration that is gained by an object due to the gravitational force. Its SI unit is ms². It has a magnitude as well as direction. Thus it is a vector quantity.

★ We represent acceleration due to gravity by the symbol g. Its standard value on the surface of the earth at sea level is 9.8 ms². Its computation formula is based on Newton’s Second Law of Motion and Newton’s Law of Universal Gravitation.

❥︎ Acceleration Due to Gravity Formula

★ Near the surface of Earth, the acceleration due to gravity is approximately constant. But, at large distances from the Earth, or around other planets or moons, it is varying. The acceleration due to gravity depends on the terms as the following:

Mass of the body,

Distance from the center of mass,

Constant G i.e. Universal gravitational constant.

$==> \boxed{ g = \frac{ Gm}{ {r}^{2} } }$

Where,

• g :- Acceleration due to gravity

$(unitsm {s}^{ - 1} )$

• G :- The universal gravitational constant,

$==> \boxed{ 6.673 \times {10}^{ - 11} N {m}^{2} k {g}^{2} }$

• m :- Mass of a very large body like Earth.

• r :- The distance from the center of mass of the large body
