Hi jtbell, thank you for your reply but that looks way above the level that I'm studying at, I'm studying second year of A level, which is like the year before you can start your undergraduate degree in England.

Thanks very much for your reply, in my Physics lesson I was told by my tutor not to use "quantity of motion" as a definition for momentum and I don't really see why, yes I've come across a few such as "mass in motion" and "the impetus of a body resulting from its motion" and wondered what was...

I know Newton described it as 'the quantity of motion' but are there any other more descriptive or better definitions? Thanks in advance!

Hello, I am having a lot of trouble in determining the difference between an electromagnetic field and electromagnetic radiation. Is an electromagnetic field caused by electromagnetic radiation within the space of which the field acts over? However if I am right a point charge that is not...

Thanks to both of you for your replies, Thank you this makes more sense now, I looked up Maxwell's equations and saw that a changing magnetic field gives rise to an electric field and vice versa. But what causes them to change, is it not that the source (the oscillating charge) is constantly...

First of all, I understand that an EM wave is created by a charged particle that is moving. What I don't understand is how it propagates itself when traveling through a vacuum as there is no medium for it to interact with. Can this be explained by anything other than photon theory? I really...
