# Why is gravity maximum at poles and minimum at equator?

Last updated at June 11, 2019 by Teachoo

Acceleration due to gravity is given by Gravitational Force

Force = GMm/r
^{
2
}

The acceleration due to gravity is given by

g = GM/R
^{
2
}

where G = Gravitational Constant

M = Mass of earth

R = Distance of object from center of earth

Earth is not perfectly spherical. Distance of center from poles is less than distance of center from equator

Since r is less in poles, g will be higher.

And r is more in equator, g will be lower.

Therefore,
**
gravity is maximum at poles and minimum at the equator
**

Let's actually find the value of g in equator and poles
