An alternative method is presented for introducing the physical quantities that are represented by vector products, namely, torque and angular momentum. The basis of the definitions of these quantities becomes evident through this approach. The reason that the position vector of a particle appears in these definitions is also clarified. The present approach can be smoothly integrated into the concepts of generalized forces and coordinates in analytical mechanics.
