Should I be good at physics to be good at programming? And what are the sources that may help to be good at physics?))

Not at all. You can learn physics at anywhere if you wish. But it is better to learn physics in a systematic way.(Colleges and Universities)

You'll only need physics, if you are planning on programming something physics related. Game physics engines yes. Most apps/websites no.
