This is likely not what you meant but,
Take any free moving object traveling in a strait line. The kinetic energy measured in that object is equal to the energy it takes to turn it 90 degrees and twice the energy it has to turn it around. What I mean is, you tried to turn the object 90 degrees, it is the same event as stopping it, and if you were to turn it around, it is the same as accelerating it back to the original speed (the forces may be different, but the total work should be the same)
In that sense we can visualize a 90 degree circular plane with an arrow piercing its center, which is a geometry that expresses
x y as the 90 degree potential vectors and
z and 2
z as the momentum or mass vector.
That is, any moving object can be expressed like this using its total energy. Nature has 90 degrees
