Answer:
I'm assuming this was multiple choice and it got cut off
The 3 things the effect the force of gravity are the mass of the main object, the mass of the smaller object and the distance between them
Step-by-step explanation:
The equation for gravity is
F=M1M2G/d^2
M1=mass of one of the objects
M2=mass of the other object
G=gravitational constant
d=distance between the two objects
Because M1,M2 and d are the only things that change, they are the variables that affect the force of gravity.
