Why Does Friction Act in the Same Direction as the Force on a Rotating Disc?

[sArGe99]

Homework Statement

"Friction hinders translation but aids rotation"
If a uniform disc is placed on a surface and a force is applied tangential to it, why is the direction of friction same as that of the force. This would surely hinder rotation and aid translation, right?

Homework Equations

This is not a problem.

The Attempt at a Solution

Out of ideas. Thought a lot about it.

I believe what they are trying to say is when the disk spins, it is pushing the surface in the opposite direction of which it is moving. Think about it: when you push against the ground, you move in the opposite direction of your push. Therefore, the friction is in the opposite direction of which it is spinning.
