No, you can impart momentum, thrust, power without being perpendicular. On the other hand being unperpendicular is a major factor in generating spin, both vertical and horisontal. Imo. And unperpendicularity to the target direction is nescessary to compensate for the incomming balls direction.

Edit: Sorry, I see this has since been discussed in http://tt.tennis-warehouse.com/showthread.php?t=450567.
