Advanced physics Definition and 58 Threads

In the United States, Advanced Placement (AP) Physics collectively refers to the College Board Advanced Placement Program courses and exams covering various areas of physics. These are intended to be equivalent to university courses that use best practices of physics teaching pedagogy.
Each AP Physics course culminates in an optional exam for which high-performing students may receive some credit towards their college coursework, depending on which college or university they attend.

    How Can I Solve This Differential Equation for x(y)?

    I'm trying to solve the following differential: ##\frac{\dot x}{\sqrt{y(1+\dot x^2)}} = \text{const}## ##\dot x## is the derivative with respect to ##y##. How do I solve it so that I end up with ##x(y)## solution ? You can find this here, but there're 2 problems: 1) I don't understand what...

    What is the Fermion's mass in this Lagrangian?

    We have a Lagrangian of the form: $$ \mathcal{L} = \overline{\psi} i \gamma_{\mu} \partial^{\mu} \psi - g \left( \overline{\psi}_L \psi_R \phi + \overline{\psi}_R \psi_L \phi^* \right) + \mathcal{L}_{\phi} - V(|\phi|^2) $$ Essentially, what we are studying is spontaneous symmetry breaking...
