Ask a Physics Question! [v.1 there must be something you don't get!]

If you're a student, this is your chance to ask those questions you feel too shy to ask in class.

If you're way past college, what things bug you about physics? What questions do your kids ask you?

This is an experiment. I hope the number of students will increase soon, so this is the time to try out something new.

I teach both physics and mathematics, so can answer anything that is in a school syllabus. I also hope that you may get answers from other physicists currently lurking in the shadows of Steemit.

Please make your questions as specific as possible. This is really aimed at physics students at school or college; possibly also university students. This is not designed to answer questions that require a whole postgraduate textbook, although you might be lucky and find an expert on the topic.

I think this is better than me writing about what I think others may want.

Any really good questions may prompt a full answer in a fresh post.
