16 Απρ 2021 · If we take the cross product of the position vector and Newton’s second law, we obtain an equation that relates torque and angular momentum: \[\mathbf{r} \times \mathbf{F}=\mathbf{r} \times \frac{d \mathbf{p}}{d t}=\frac{d}{d t}(\mathbf{r} \times \mathbf{p})-\frac{d \mathbf{r}}{d t} \times \mathbf{p}\label{11.7}\]

13 Σεπ 2023 · There is a similar expression for angular momentum - when a system experiences a change in angular momentum \(\Delta \vec{L}\) over a time period \(\Delta t\) due to an external interaction of some kind, we can model that interaction as delivering a torque \(\vec{\tau}\) to the system, defined as
24 Απρ 2022 · The action of a torque causes a change in angular momentum, as expressed by Equation 5.7.1. A special case arises when the torque is perpendicular to the angular momentum: in that case the change affects only the direction of the angular momentum vector, not its magnitude.
Torque is defined as the moment of force or turning effect of force about the given axis or point. It is measured as the cross product of position and force vector while as angular momentum is the rotational analogue of linear momentum.
