usually the value of g, is taken as 9.8 m/s sq.
if an object is thrown verically upwards we take it as -9.8

what will be the value of g if an object is thrown in a circle or curved form?

There are slight variations in the value of g about earth's surface. These variations result from the varying density of the geologic structures below each specific surface location. They also result from the fact that the earth is not truly spherical; the earth's surface is further from its center at the equator than it is at the poles. This would result in larger g values at the poles. As one proceeds further from earth's surface - say into a location of orbit about the earth - the value of g changes still.
