Alert
Recently I gave my science tution teacher the SA1 science paper...
And he discovered....
that 1 off the question has an error
take out your exam papers...
and turn to question 33
Answer for Part a) should not be A
it should be they are the same
Answer for part b) should not be A is the starting point with the highest.....
It should be:
Gravitational poteintal energy is about height,
in this case if the height is the same, then there should not be a change in G.P.E
so therefore they have the same amount of G.P.E
Could someone E-mail Mdm.Ho on this question?
I will update some pictures and videos to suport the answer...
Thank you
