Hi all, I am very confused about the graphs of gravitational potential and gravitational field strength... I know that both gravitational field (g) and electric field strength (E) are negative gradient of their corresponding potential (Vg and Ve). If so, shouldn't g and Vg graph look very much similar to E and Ve graph? However, most graphs regarding g and Vg show that graph of g exist in the first quadrant while that of Vg exists in the fourth quadrant. But for electric potential and field, the graphs of both quantity exist in the first quadrant. I find this very confusing as both relationships (g/Vg and E/Ve) are essentially the same. Any explanation would be appreciated. Thanks!
