    Potential Energy: Rigorous Understanding & E=mc²

    This seems interesting. I believe with potential you are talking about scalar potential of the helmholtz decomposition. But idk much about that. Instead of pointing issues in the view I mentioned, can you please give me your detailed view of PE? Thank You.

    Potential Energy: Rigorous Understanding & E=mc²

    I mean by Internal Forces, forces operating within different parts of system, whose dynamic effect cancels out (forming action reaction pair).

    Potential Energy: Rigorous Understanding & E=mc²

    I used to believe that potential energy of a particular particle is of no meaning. It is always linked with a system, and Potential Energy of a system means negative of work done by INTERNAL conservative forces from an initial stage of assumed zero potential energy. And energy cannot be said to...

    How to start LM317 regulator from 0 Volts

    Thank You I will try considering that. Can you tell me a negative compliment to Lm10?

    How to start LM317 regulator from 0 Volts

    I am actually making a dual power supply with lm317 and lm337. So I do have negative supply. So I can use another regulator to generate the -10V or -1.25V. But problem is that I want to boost the current using transistor and I want to use the protection diodes as well. But I don't have enough...

    How to start LM317 regulator from 0 Volts

    I started to think if I apply load across R2 the current it needs should come from R1 but ideally Curreny thru R1 is constant. Thus regulatuon will be destroyed. Isnt there another way to getting from 0V output where I can apply those additional capacitor and diodes for protection and additional...

    How to start LM317 regulator from 0 Volts

    I want to make power supply from LM317 which starts from 0 volts instead of 1.25 volts. I have seen method of using diodes and zeners but I think there maybe a better way. We know Voltage across R1 (see image 1) is 1.25V. So if I take the output across R2 rather than at OUT of IC, won't I get...

    Pressure exerted by a gas (derivation using the kinetic theory of gases)

    Its because yoy want to find average force exerted by the molecule. How u find average force? See u find the time in which this repears aka time period. The collision with wall PQRS repeats. Now find the average force in this time. If u were to find instantaneous force u have to divide by time...

    Studying Am I Doing Good? A Junior College Physics Aspirant

    I am in First Year Junior College (almost at its end). I literally love Physics. I want to become a Physicist. I want to be capable of explaining any phenomenon in terms of Physics. I love solving complex, interlinked numericals. I am one of the fastest one to solve them. But I feel I am not...

    Force & Torque: Acceleration, Power & Angular Velocity

    How can Force, sometimes instead of accelerating moves an object with a uniform motion. And how Power equals force into speed if force should accelerate. What does torque do, accelerate angularly or move object with unform angular velocity. How Power equals Torque into Angular Velocity if torque...

    How does the sign convention work in ray optics?

    Thank you everyone. I have mastered all the topics in my portion.

    How does the sign convention work in ray optics?

    Thank you. One last thing, we have studied ray optics with approximations. Like in mirror equation and Magnification power. For eg we have assumed tan of theta is appro theda for small values. Thus can have been able to derive formula. But is there any possible way to derive all those formulae...

    How does the sign convention work in ray optics?

    The one I use is left side of mirror lens is negative right is positive. Above the principle axis positive below is negative. Acc to that I talked about negative sign in Linear Magnification formula, but for mirrors only. For lens the formula should be correct. And yes the comment is about...
