    That works now, thanks very much

    Electric field between two capacitor plates (proof)

    The forces act in the same direction so I assumed that I add them? The two terms come from the forces from the left hand side plate and the right hand side plate

    What Determines Gravitational Potential Energy?

    Intuition tells me that that’s the gravitational potential energy of the system- but I’m unsure. As a little exercise I considered a free and a stationary mass and reasoned that the free mass finishes with all the energy, which is equal to the loss of GPA. This led me to think that the total...

    Undergrad Understanding Redshift: The Role of Relative Motion between Emitter and Absorber

    As light interacts as a particle and when being absorbed or emitted by an electron that is done instantaneously, that is, no time between the photons energy not being contained (I’m unsure as to whether or not this is the correct word) within the electron to being contained within it, how does...
