1. As you know,they give the formulas,but my teacher says that they miss 2 formulas out(we have to memorise these formula)

My question is which are the two forumulae that AQA miss/do not give out?

Thanks

2nd question:Will questions that require the formula(the two that are not given to us) guarantee to pop up in the Physics exam?

Thanks
2. Hiya,

If you go on the AQA website and look at the data sheet it will show you which formulas they give you. It shouldn't matter though because from the formula that they give you, if you're not confident with rearranging straight away, you should be able to draw the triangle and work out the formula from there. The physics GCSE is about 40% equations, most of them are in the form given in the data sheet but there are a few that they slip in to challenge you where you will need to rearrange.

So they give you all,but you may be have to rearrange them?

My teacher said that they leave two formulas out?

Hiya,

Most of the equations only have 3 variables such as speed = distance ÷time.

They will give you 1 variation out of the 3 such as they will give you speed=distance÷time but if you need to work out distance or time (the other 2) you will have to rearrange the formula that they give you.

E.g. from speed=distance ÷time

Rearrange for distance
Distance=speed×time

Rearrange for time
Time=distance÷speed

I think this is what your teacher means. Just ask if you need anymore help
