momentum
Explanation:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass, energy and electric charge.
On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration, momentum and velocity.

Answer is:
constitute a couple
Explanation:
The two equal and opposite forces, whose lines of action are different, form a couple.
A little consideration will show, that a couple does not produce any translatory motion (i.e. motion in a straight line), but a couple produces a motion of rotation of the body on which it acts.
