Applied Force in a Non-inertial Frame

Let us consider two reference frames: $S$ and $S'$. $S$ is an inertial frame and $S'$ is a non-inertial frame as it is rotating wrt $S$ with an angular velocity $\omega$ about a fixed axis. The origin …

Lagrangian for Non-inertial Frame

Context Let us consider two reference frames: $S$ and $S'$. $S'$ is rotating with respect to $S$ with an angular velocity $\vec{\omega}$ about a rotation axis $MOM'$. The origins of $S$ and $S'$ are …
