Question

The force of gravity between two objects is directly proportional to which of the following?
a. the masses of each object.
b. the velocity of each object.
c. the distance between the objects squared.
d. the mass of one object and the distance between the objects.

Answer 1

Force of gravity =Gxm1xm2 /r^2 G= gravitational constant m1 and m2 are masses r is the distance between masses. So a is the correct option

Answer 2

The force of gravity between two objects is directly proportional to the
product of the two masses, and to the mass of each object individually.
