Formula: Work Done by the Force of Gravity (W = mgh)

CISCE: Class 10

Formula: Work Done by the Force of Gravity (W = mgh)

W = FS = mgh

$W$ = Work done
$F$ = Force = $m g$ (weight of the object)
$S = h$ = Vertical displacement
$m$ = Mass of the object
$g$ = Acceleration due to gravity
$h$ = Height moved
