This sounds daft but my son has had a test on moments in science.....to do with pressure.
The question he had at age 14 showed a child on a see saw on the left end and nobody on the other and the question said what force is being applied;
Well sounds obvious but most kids put simply DOWN as the answer.
My son had read a revision book and this book showed exactly the same sort of see saw and said it was an anticlockwise moment...
So thats what he put but his teacher said its wrong and should just have been Down.
Anybody know if my son was right or wrong.
Not really too bothered as it was a little test but the problem i now have is he says he is never going to look at revision books again as they give wrong answers. We have only just tried to get him to read round subjects and this has thrown everything in the air. If someone can say either he is right or that he is wrong and misunderstood the revision book i would appreciate it.
