## Main Question or Discussion Point

Why are Newtons law of universal gravitation,

[itex]F=G\frac{m_{1}m_{2}}{r^{2}}[/itex]

and Coulombs law,

[itex] F = K_{e}\frac{q_{1}q_{2}}{r^{2}}[/itex]

inverse square laws? I understand why they are inverse because the force decreases with distance but why is the distance, r, squared?

Thanks
