# Physics - Angular Momentum

When the angular momentum changes, the 'change' in the angular momentum vector (ie. dL) is ____.

[a.] perpendicular to the torque vector.
[b.] parallel to the angular momentum vector.
[c.] parallel to the torque vector.

.. im confused on this one.. i think it's [A]. am i right? :\

No, (a) is incorrect. Just as acceleration or momentum change is parallel to the force causing it, the change in angular momentum is parallel to the torque causing it.

thanks. i had a feeling it was (C)..
