I think I might understand now. Since: \dot{x}=\frac{dx}{dt} \ \ \ \dot{y}=\frac{dy}{dt} \ \ \ \dot{z}=\frac{dz}{dt} Then: \dot{x}=\frac{d(rsin \theta cos \phi)}{dt} \ \ \ \dot{y}=\frac{d(r sin\theta sin\phi)}{dt} \ \ \ \dot{z}=\frac{d(rcos \theta)}{dt}. And since dr=dr \hat{r} + r...

I'm not quite sure what you mean by that?

Homework Statement Derive the expression for kinetic energy of a classical particle in spherical coordinates. Homework Equations I believe the answer I am supposed to reach is: T=\frac{1}{2} m (\dot{r}^2 + r^2\dot{\theta^2} + r^2\dot{\phi ^2}sin^2\theta) The Attempt at a Solution...
