	Tidal [[force]]s are changes in the [[gravitational potential energy]] of the [[Sun]], Moon and Earth. These forces cause the periodic motion of the seas which create a temporary change in [[water]] levels that vary depending on location. Due to the [[inverse square law]], the side of Earth closest to the Sun or moon will experience a greater force than parts further away.<ref name=Ref1>Chris Mihos, Department of Astronomy, CWRU.
