势能=Potential Energy (简称PE)重力势能=Gravitational Potential Energy (简称GPE)根据这个公式:Mechanical energy=potential energy+kinetic energy我想问的是,这里的potential energy是没有计算公式的,至少在我们书上是没有的,所以不可能涉及到,但是GPE是有公式的,GPE=mass·9.8m/s²·height.是不是potential energ...
引力场计算中的potential和potential energy的表达式中的符号问题总是大家搞不明白的地方,这个其实大家熟知的定义有关系,下面给大家梳理一下正确的思考路径供大家参考。 首先严格的potential的定义是需要我们明确的,这是必须搞清楚的地方且不能存在争议的地方。 Gravitational potential: work done(by external agent) per...
Inverse Square Law,即平方反比定律,就是与某变量的平方成反比,万有引力定律公式即是这个特性,距离越大,互相引力与距离的平方成反比(1/r^2)。inverse square nature of gravity force是指重力的平方反比特性,即距离越远,互相引力越小。下文是指把无穷远处作为参照点,那么重力作用为0(r趋近无...
场强为零,电势不一定为零,因为电势是个相对量 The electric potential is, with the gravitational potential energy which relative says is same, does not have the frame of reference has no way to say its potential energy is how many. Likewise does not select a zero potential spot, is does not ...
重力勢能由於物體所在的位置受重力作用而引起(GravitationalPotentialEnergyofanObjectduetoitsPositionundertheActionofGravity)l因為重力場(即地心吸力)嘅存在,位置較高嘅物體會較其他位置較的嘅物體有較多嘅內能(存在喺物體入面嘅能量)。n依個內能就叫“重力勢能”。n要引證依點可以攞起一件物體然後放手。因為有重力...

Gravitational Potential Energy Formula Gravitational potential energy is a concept in physics that describes the energy possessed by an object due to its position within a gravitational field. This energy is dependent on an object's mass and its height above a reference point. The formula to calcul...
