Hey! New to this site, started taking physics yesterday and already need some help 1)My textbook is very complicated, is there an easy way that anyone can explain what scalar components are? 2)I did a lab with a force table and 3 pulleys. You add weight to one pully to even out a ring. I'm sure plenty of you have done this before. If you have, could you explain to me how you measure in that lab...thanks. Thanks for any help I may recieve!
