能量、力、场与洛伦兹力公式

Energy, Forces, Fields and the Lorentz Force Formula

Artice M. Davis

摘要:

我们对运动粒子的能量作一个简单的分解.基于这种分解,我们确定的潜在的和动能,然后使用它们来给出一般的定义的动量和各种力施加在粒子上的领域,其次是牛顿第二定律的推广,以适应这些一般定义的力量。我们表明,我们的推广意味着洛伦兹力定律以及拉格朗日方程,以及通常接受的拉格朗日和相关的速度依赖的潜在的一个移动的带电粒子。

英文摘要:

We apply a simple decomposition to the energy of a moving particle. Based on this decomposition, we identify the potential and kinetic energies, then use them to give general definitions of momentum and the various kinds of forces exerted on the particle by fields, followed by the generalization of Newton's second law to accomodate these generally defined forces. We show that our generalization implies the Lorentz force law as well as Lagrange's equation, along with the usually accepted Lagrangian and the associated velocity dependent potential of a moving charged particle.
