Similar question https://stats.stackexchange.com/q/17595/99274 I gave a physical [answer]( https://stats.stackexchange.com/a/324197/99274) to that which addressed moments.

"Angular acceleration is the derivative of angular velocity, which is the derivative of angle with respect to time, i.e., $ \dfrac{d\omega}{dt}=\alpha,\,\dfrac{d\theta}{dt}=\omega$. Consider that the second moment is analogous to torque applied to a circular motion, or if you will an acceleration/deceleration (also second derivative) of that circular (i.e., angular, $\theta$) motion. Similarly, the third moment would be a rate of change of torque, and so on and so forth for yet higher moments to make rates of change of rates of change of rates of change, i.e., sequential derivatives of circular motion...." 

See the [link]( https://stats.stackexchange.com/a/324197/99274) as this is perhaps easier to visualize this with physical examples.
