It says jan 02 at the top, my teacher collected some papers with stuff that is in the syllabus for us to solve and this is one of the questions

ABF:
does anyone have any notes for revision for physics 6PH01...

wakemeup:
Could someone please explain 22ci and ii of the edexcel sample paper. According to the mark scheme T=wsin40 which doesn't make any sense. My perception of the diagram is probably wrong.

Igcseboy:
Hey

2morrow is the 6PH01 paper

so i have some questions

in free body diagrams from where we should draw the contact force??

and anybody have notes on projection.....

any important points on the speed time graphs and all ???

i can understand wat to do as the portion for unit 1 is too small i guess

any suggestions on wat i shud do
