Answer:
The attractive force that occurs between the sun and the earth called <em><u>gravity</u></em>.
Explanation:
Gravity : A force between two objects which attracts each other towards itself.It is mathematically directly linked to the product of masses of both object divided by the square of the distance parting the two objects.

F = Gravity or gravitational force
G = gravitational constant
m ,M = masses of objects
r = distanced between the objects
Where as friction is a force between the surfaces of two bodies , magnetism is the force that can attract or repel and weight is the force exerted by the earth's gravity on object to pull it towards the center of the earth.
