Confined in a box, what is the average distance between a particle hitting a side? @tpg2114 given that this problem is so common in kinetics, could you provide a link to a website explaining it? |

Am I faster than my shadow? Imagine a much slower speed of light. If you accelerate, the speed of your head's shadow will be slower as the ground is recieving light (and information about the blockage of light) from yourself a few seconds ago. Note that I'm assuming detectors on the ground, not eyes, measure the speed of shadows. |

Confined in a box, what is the average distance between a particle hitting a side? That's only for the top edge of the square, and $\theta \ne 0$ anywhere on here, so there is no problem. For the other sides, make a phase shift of $\pi$ or $\pm \frac{\pi}{2}$ |

Directionality of angular momentum A teacher. If it was a book I would cite it. |

Directionality of angular momentum The problem I was having is that he seemed to imply that the value [sum of all linear momentum] could grow or shrink to [sum of all angular momentum]'s loss or gain (losses/gains are equal in magnitude). On reflection, I think he may have just been wrong, but I wanted to check here that I wasn't being an ignoramus. |

Directionality of angular momentum It was an implicit assumption, as with any momentum conservation questions. |

Is there a mathematical derivation of potential energy that is *not* rooted in the conservation of energy? Thank you for the mathematical description. Is there nothing more to energy and work other than 'a value that is conserved' (although not conserved in the same way, or course)? |

Is there a mathematical derivation of potential energy that is *not* rooted in the conservation of energy? Where does the equation for work come from? Is that form its definition, or is it empirically based? And is kinetic energy defined by anything, or did physicists mould the equation for it around to fit an everyday thing? |

Is there a mathematical derivation of potential energy that is *not* rooted in the conservation of energy? Sorry, I forgot to specify that I was considering about only conservative forces. |
