If two balanced forces act on an object in opposite directions then that object will remain stationary.
Opposites also hold each other in balance and exert mutual control.
Balanced forces exert mutually on an object making it remain stationary .
What is likely to exert mutually on an object, making the object remain stationary?

  balanced forces
  kinetic energy
  a single force
  competition
  unbalanced forces
  heat energy
  randomized forces
  solid, liquid, gas
