WJEC Core!

  • 0 votes

I'm trying to revise for basically all the topics we have covered in physics for the core exam in June, I'm doing higher tier and I find the subject really really hard, although I'm doing higher tier which makes no sense at all...Does anybody have any sheets or anything really on the equations particulary? I don't understand how to work out the different maths they ask you to do, especially when you have to re-arrange it to suit the question. If anyone could help, that would be amazing:-) thanks!

For rearranging the equations try and put them into a triangle format like

for distance= speed x time do


s  x   t

simply cover up the letter you want to find and you are given the new formula

for finding speed do

s= d or speed = distance / time


It's hard for me to explain but I hope it helps, I'll upload a picture of what I mean in a moment.
