The gravitation, or the gravity, is a force that attracts all objects that have mass, towards the surface of the earth.

The earth rotates in a circular orbit around the sun and the gravitational force provides the centripetal acceleration.

The equation of the velocity of the earth around the elliptical orbit is expressed as:

$v=\sqrt{\frac{GM}{r}}$

Here, $V$ is the speed of the earth, $G$ is the gravitational constant, $M$ is the mass of the earth and $r$ is the distance between the earth and the sun.

According to the above equation, the distance is inversely proportional to the speed. The earth and the Sun are closer in November than May. Hence, the distance between the sun and the earth decreases in November.

Thus, Earth moves faster in its orbits in November as compared to may.
