    Conservation of angular momentum - tetherball vs charged particle

    Are you referring to the induced emf that would accompany a *changing* magnetic field?

    Conservation of angular momentum - tetherball vs charged particle

    So then can you say whether or not this tetherball will be accelerating or not?

    Conservation of angular momentum - tetherball vs charged particle

    I've already mentioned that the electron cannot be accelerated because there is no work done in the direction of motion. F produced by the magnetic field B will always be perpendicular to the particle (let's just say it's a positron for clarity of discussion). I'm going to be assuming that the...

    Conservation of angular momentum - tetherball vs charged particle

    I'm not quite sure how your comment on the charge is relevant? The opposing forces you're talking about which I assume to be instances of Faraday's/Lenz's Laws apply to fluxes varying in time. Let's consider a situation where you instantaneously increased the [uniform] B field so that the...

    Work in a PV Curve: Is the Work Done 0?

    Hey all, In one of my textbooks, there is a passage in the thermodynamics section that states that: For a closed cycle where the system returns to its initial state, the work done is the area enclosed by the curve (when looking at a Pressure-Volume graph). Shouldn't the work done by...

    Conservation of angular momentum - tetherball vs charged particle

    Hey all, I was wondering if one of you could help me out with a debacle I'm having. I'm having trouble reconciling what exactly happens between an orbiting tetherball and the separate scenario of a orbiting particulate charge. With the particulate charge: you can, given the velocity and...
