How is gravity affected by mass and radius?
Answer (2)
Gravity is directly proportional to the difference in mass ( thus, the greater the difference in mass of two objects, the greater the gravity).
Gravity is inversely proportional to the square of radius between two objects ( thus, the greater the distance from radius, thus, the lesser the gravity)
Well if you mean the radius of an object, then it is directly proportional; greater the radius, greater the gravity.*
Gravity is influenced by two main factors: the mass of the objects involved and the distance between them. The force of gravity increases with the mass of the objects and decreases with the square of the distance between them. This relationship is captured in the equation F = G R 2 M 1 ⋅ M 2 .
