This comment is being downvoted but it's correct. The moon all moves at the same speed, which is the speed at its center of gravity. The face nearest us is moving slightly slower than it should at that distance so it is pulled towards earth. The far side is moving slightly faster, so it is pulled away from the earth. The wiki link explains it pretty well. https://en.m.wikipedia.org/wiki/Tidal_force https://en.m.wikipedia.org/wiki/Tidal_force
