Ok great, thanks a mill :)

The spring is vertical and the question does not give the mass of the spring.

well I thought with no mass the force is zero but then is the k equal to x? See, i was getting a big answer then for x and it didnt seem like the right answer. I am definitely missing something very obvious here

Can I find out the natural extension of a spring if I am only given the mass of a block that can be put on it and the value of the spring constant? I have found x ( from the formula F = -kx ) when the block is on it but I now need to find the extension of the spring with no mass on the end. It...

Thank you everyone. I am revising for an exam and i think i was just overloaded with the different ways of defining Ampere's Law on google and I just wanted the easiest way to state it as well as a way to best comprehend it. I have found all of your answers helpful and BOAS I now know for sure...

Could someone give me a word definition of Ampere's Law as I have googled some definitions and they all seem a bit confusing. Thanks :)

Thanks a mil! Ya I was talking about G in Newton's Law of Universal Gravity. So I can use G ( 6.67×10−11 N m2/ kg2 ) for all planets. Thank you for your help Doc

Quick question... Can the gravitational constant only be used for Earth or can it be used in questions regarding other planets?

Thanks jtbell, just had a look at the link and this is also really helpful. Thanks a mill :)

That is great, thanks a million! It is much clearer to visualise now. :)

Could anyone help my with proving that the acceleration of an object that is moving with uniform circular motion is directed towards the centre of the circle and is of magnitude ω^2(r). Thanks
