What do you mean free fall?

${\large{\mathscr{\underline{\red{ Answer:-}}}}}$

Earth's gravity attracts each object to its center.When an object is dropped from a certain height,under the influence of gravitational force it begins to fall to the surface of earth.Such am object movement is called free fall.

Symbol $\red{\longrightarrow}$g

SI unit $\red{\longrightarrow}$ ${ms}^{-2}$

Formula $\red{\longrightarrow}$g=GM/r²

Dimensional formula $\red{\longrightarrow}$${M}^{0} {L}^{1} {T}^{-2}$
