### Variable for frequency

Is there another variable that is used to represent frequency? It can be confusing when E=hv and Ek=(1/2)meve2 and the v is also velocity.

I guess you could replace nu (the greek letter that stands for frequency and looks like a V) with Hz so that it could be easier to differentiate in your own work, but I would make sure to be careful because the question will most likely give you the frequency with a V instead of Hertz.

To my knowledge, there aren’t any other variable you could use to differentiate frequency and velocity. You could just curve the v to differentiate it from a normal V.

No, to my knowledge there isn't another variable to use, but the v for velocity and v for frequency are normally written differently (i.e the v for frequency is usually curvy-ish). However, if you want to replace v with another variable you can either write in nu as recommended before or make your own key to use! (Just make sure to make it clear on tests/ homework probably and don't use variables used elsewhere either.)

### Re: Variable for frequency

Just to clarify further, v is for velocity while nu is for frequency.

### Re: Variable for frequency

My high school teacher used lowercase "f" to represent frequency, which was pretty useful in the context of high school chemistry, and which wasn't ever confused with v or even capital F for force. I'm not sure if a new variable "f" will be introduced later on, but this has worked for me.
