Answer:

Torque produces angular acceleration in rotational motion.

Explanation:

Torque plays the same role in rotational motion that force plays in linear motion. Through Newton'a Second Law you know that force #F# acting on a body of mass #m# produces (linear) acceleration #a# according to:
#F=ma#
In the same way a net torque #tau# acting on a body of moment of inertia #I# causes it to undergo the angular acceleration #alpha# as:
#tau=Ialpha#
