Thanks for the reply! Part of the confusion was caused by me thinking that centripetal force (Fc) was meant to be included in the force diagram. I've read elsewhere that Fc is simply just the "net force" and is equal to (reaction force - mgcos(x)) or (mgcos(x) - reaction force). So the only two...

There you go! :)

Hi, if you consider a ball, with mass m, rolling down the outer surface of a hemisphere with radius r, why is it that if you consider the forces acting upon the ball and resolve in a direction, the equation formed is: mgcos(x) - R = m(v^2)/r If you rearrange that, it would appear that the...
