One distinguishes scalars from vectors by the number of quantities specified. A vector has magnitude and direction. A speed might be stated as equaling 50 km/h and so might the magnitude of a velocity. But the velocity will have an additional quantity, such as 090�, to indicate direction. Torque magnitudes are given in newton meters but that says nothing about the direction of the vector.
