Expert Answer:

The earth is moving around the sun due to this it has some value of acceleration. But for all the bodies on the surface of the earth , there are two forces acting, one is the gravitational force and the other is the psuedo force due to the acceleration of the earth. Since the gravitational force almost nullifies the psuedo force, that is why there is no9 effect of earth's movement on the bodies of the earth due to the gravitational force. That is why the earth is considered as an inertial frame of refernce.
