When the object falls towards the earth due to the earth’s gravitational force, it something we call as free fall of the object. So during the free fall, the only force acting on the object is the gravitational force of the earth. The acceleration due to gravity is the acceleration produced in the freely falling body due to the influence of the gravitational pull of the earth
Acceleration due to gravity is denoted by ‘ g ‘ but its values vary. Like, for example, the acceleration due to gravity on the moon is different from that of the earth.

Hey mate here is ur answer....
Radius of equator : As Earth is flattened at the pole , radius of the equator is greater than radius of the pole. Since gravity is inversely proportional to the radius. This factor reduces the net gravity at equator compared to the pole.
Centrifugal force: At equator centrifugal force acts outward i.e opposite to the direction of force of gravity which acts towards the center of the Earth. Thus again, reducing the gravity at equator. However, centrifugal force at the pole is zero.
Mass: As Earth has more mass at equator (larger radius of equator compared to pole) , this particular factor increases the gravity at equator....
