Can charge flow between two equipotential points?
For simplicity take a one-dimensional case along $x$-axis. Place a positive charge $q$ at a point A. We will prove it can reach a point B at same potential only under electric force.
$F=qE$
⇒$a=qE/m$
⇒...

Finding the normal component of acceleration for constant speed along a curve at any point in time [closed]
I am trying to find the normal component of acceleration for a particle moving along
$ y = sin(x) $ at constant speed $2 \frac{m}{s}$ as a function of time. I know $ a_n = \frac{x'^2}{\rho}$, $ \rho = ...

Kinetic energy and reference frames [duplicate]
Speed is relative i.e. different frames of reference can measure different speeds of a body. This means that kinetic energy is also relative. So does it mean a frame of reference can measure the ...

How to find the real net force on an object observed from two frames seeing each other to be accelerated?
A frame $S'$ is moving in the right direction at acceleration $1m/s^2$ w.r.t. $S$. (It is not mentioned which one is inertial and which one is not. So, $S$ sees itself to be inertial and $S'$ to be ...

Should I explain this by Pascal's principle or simple Pressure/Force relationship?
I have a simple demonstration where two syringes are connected by a narrow tube, and one syringe has a wider diameter than the other. When you try to "compete" by having two people squeeze ...

Representation of electrostatic force with rubber bands and balls [closed]
I had a question in my mind, can we use the analogy of an elastic string(say a rubber band) and a couple of balls, let's say we need to show attraction, then we can say the two balls are on either ...

Doubt regarding inertial and non-inertial frames of reference
Consider a body falling to the surface of a planet (through vacuum)
To the body, would it register itself as an inertial frame of reference while the planet's surface accelerates towards it, hence ...

What accelerates when a force changes the shape of a body?
When a force is applied to change the shape of a body (such as squeezing a ball of clay), what is being accelerated here by the force? Is it the particles of the clay since there is no linear motion ...

Relationship between these two definitions of angular momentum
I learned in (1) that the angular momentum of a particle of mass $m$ at position $\mathbf{r}$ travelling at velocity $\mathbf{v}$ is an element $L\in\mathfrak{so}(3)^\ast$ defined by $L(X)=\mathbf{r}^...
