Forces that are equal in size but opposite in direction are called balanced forces.
The body on which these two forces act will not accelerate.
The forces are unbalanced when they are not equal in size. This will result in a change of motion.
action-reaction forces
Size: the same. Direction: the forces are in opposite directions.
It tells us that the sizes of forces are equal and directions of forces are opposite.
When two forces cancel each other out, -- their magnitudes (size) must be exactly equal -- their directions must be exactly opposite.
Zero force. F-F=0

Because the forces are acting on two different objects
