You are presented with the question "the mass of an object causes the what exerted by that object?" and the following answer choices: 
- electromagnetic energy
 - Electrical energy
 - attractive force
 - heat energy
 - friction
 - solid, liquid, gas
 - energy of moving objects
 - kinetic energy

Now knowing that the mass of an object causes the gravitational force exerted by that object and all gravitational forces are attractive, there is no repulsive gravitational force, choose the best answer.


 

   attractive force
