Fact 1: If two balanced forces act on an object in opposite directions then that object will remain stationary.

Fact 2: Opposites also hold each other in balance and exert mutual control.

Given the two facts above, answer the question "What is likely to exert mutually on an object, making the object remain stationary?" with the following options: 
- balanced forces
 - kinetic energy
 - a single force
 - competition
 - unbalanced forces
 - heat energy
 - randomized forces
 - solid, liquid, gas
