So I was doing my calc homework when I stumbled upon this thought: lets say you were trying to find the solid of rotation of y=x^2 around the x-axis over the interval [-2,2]. the traditional method would entail pi * integral from -2 to 2 of (x^2)^2 dx while this is easier for a simple...

I just don't understand why. Gravity is usually a force, so wouldn't that affect acceleration and velocity?

I am not well versed in complex physics (I've taken honors physics in High school) so any help I can get with simpler vocabulary would be appreciated. I stumbled upon this problem when just thinking and have not been able to find an answer. We all know that gravity affects photons, as...
