Post your doubts in Physics

To moderators,

I hope I am allowed to start such a topic. If not, please let me know and I will desist from doing so in future.

To all members,

Physics is one of my favourite subjects. Please post your doubts in Physics here. I do not claim that I will be able to answer everything. But I find that most of members here are of very young age. Many are as young as 13 or 14 years. Therefore, I have confidence that I will be able to answer most (if not all) of questions in Physics that you post here.
