## Main Question or Discussion Point

If F denotes the central force and is given as the inverse of the square distance

F=-k/r^2. where k>0. How can i show that F the path of the partilce under that force is a conic?

What i can see is that it is the second law of Kepler. And when i try to compare F with the former equation of conics r= (pe)/(1+ecosB). I can find p!

Just i need your help
