WebRelation between angular momentum and torque: The angular momentum of a particle is given by. L ⇀ = r ⇀ × p ⇀. Differentiating both sides of the above equation with respect to t, d L ⇀ dt = d dt ( r ⇀ X p ⇀) = d r ⇀ dt × p ⇀ + r ⇀ × d p ⇀ dt. Now d r ⇀ dt = v ⇀ and, d p ⇀ dt = F ⇀. Therefore equation (A) becomes.

WebAnswer (1 of 5): Determining the angular momentum from the torque can be done using the equation \tau = \frac{dL}{dt} in exactly the same way as determining momentum … WebThe torque vector points along the axis of rotation, in one of two directions. This means that the torque vector is always perpendicular to the applied force and the moment arm. The formula for torque depends on the cross product of two vectors, which was presented in a previous section.
