Thanks, that's really helpful, at least I know I'm pretty much certainly right. Thanks again,

Just done the calculation again, I'm fairly sure I did the calculation right and I got the same answer. It might be a problem with units, not sure. I'm just going to go with 2.48E-54 and hope it's right, I can't see any problems with my calculation at least

Okay thanks. I understand the difference between G and g but it's still been helpful just to get a bit of background knowledge anyway. I think I'm good as far as the history goes now, I'm just getting down to writing about the limitations of a pendulum. Modelling it as ideal, energy lost, that...

Okay, I didnt think there was anything wrong with the maths it just seemed to be a ridiculously tiny number. The next questions asks us to compare it to see the possibility of it being a black hole, so I just thought they would be reasonably close. I guess it makes sense to be far smaller...

1. Calculate the schwarzschild radius of a proton 2. R = (2MG)/c^2 3. I plugged in m= 1.67E-27, G=6.67E-11 and c=3E-8 and got out an answer of 2.5E-54. This seems ridiculously small, but I can't figure our if I'm doing something wrong or if it really is just that tiny. The next...

Hi, I have to write a report on measuring g using a simple pendulum and I wanted to get a bit of the background. I understand that a pendulum was the best way to measure g up until about a century ago but did we use anything before that? Also what kind of methods have taken over? I've tried...
