Is it impossible to construct a Faraday cage that can block a *static* electric field?
I think the answer is yes. My reasoning is this: Imagine for argument's sake, we could have a charged negative source that has its field blocked by a Faraday cage. We can transport a positive charge ...

How does a transfer of chemical potential energy occur in a circuit?
I am aware that simple DC circuits use a battery which is connected to several elements. In the case that the element is a resistor, I read that the circuit as a whole is an isolated system for energy ...

Intuitive explanation that mechanical energy is conserved in gravitational field
Suppose you have $n$ particles with masses $m_1, \cdots, m_n$ with position vectors $\vec{r_1}, \cdots, \vec{r_n}$. Now without any forces except gravity acting on them, conservation of mechanical ...

Conservation of energy in a uniform electric field
Say you place a positively charged particle between two plates with an uniform electric field between them. The particle will accelerate towards the negatively charged plate with a constant ...
