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 FF acting on a body of mass mm produces (linear) acceleration aa according to:
F=maF=ma
In the same way a net torque tauτ acting on a body of moment of inertia II causes it to undergo the angular acceleration alphaα as:
tau=Ialphaτ=Iα
