1. The problem statement, all variables and given/known data
The direction of a force is the same as the direction of the acceleration this force is creating on a moving object. And the direction of the torque? I am just questioning myself.

2. Relevant equations

3. The attempt at a solution

$$\vec{N} = \vec{r} \times \vec{F}$$

where N is the torque, r = moment arm, F = force

torque is perpendicular to both the moment arm, r, and the force F.
To determine the direction you have to use the right hand rule

your fingers point in the direction of the moment arm and the palm in the direction of the force.

Yes, I know that. And the answer to my question is that the torque is in the direction of the change of angular velocity. Thank you, I should have worked a little more before asking.
