Troubleshooting LATEX in Physics Section

[bacon]

I am trying to post a question in the physics section but the LATEX is misbehaving. It seems to be stuck on the equation for kinetic energy. Any LATEX command I put in always shows up as the kinetic energy equation.
Any ideas on how to fix this?
I have closed the web browser and opened it up again and have tried a different browser altogether.

Sorry, I see the answer to my question in another post.
