Action and reaction:- (For a given system)
(a) Act on the two different objects
(b) Have opposite directions
(c) zero resultant

Action and reaction (i) act on two different objects (ii) have equal magnitude (iii) have opposite directions (iv) have resultant zero

Action and reaction are always equal and opposite and act on

Action and reaction are forces acting simultaneously and acting on same object.

Do action and reaction act on the same body or different bodies ? How are they related in magnitude and direction ? Are they simultaneous or not ?

What will be the resultant force when two forces act in opposite directions on an object?
