Torque is classified as a vector quantity because it possesses both magnitude and direction. The discussion highlights the confusion that can arise when considering torque in introductory problems, where forces often act in a single plane, making the orientation (clockwise versus counterclockwise) more relevant. Participants agree that while torque can seem scalar in simple scenarios, its vector nature is confirmed by its directional attributes. The distinction between scalar and vector quantities is emphasized, with scalars having only magnitude. Ultimately, torque is recognized as a vector due to its inherent directional characteristics.
