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

Fact 2: If an object is at equilibrium, then the forces are balanced.

Given the two facts above, answer the question "What happens when an object is at equilibrium?" with the following options: 
- It melts
 - It remains stationary
 - The bending of a ray of light
 - It weighs more
 - matter vibrating
 - It moves quickly
 - flow of electrons
 - Movement of an air mass


 

  It remains stationary
