The physical quantities that remain constant are more than two. They include:
Speed, v
Scalar acceleration, v^2/r
Angular momentum, mvr
Kinetic energy, (1/2)* mv^2
Mass m
force, mv^2/r
The item stays in one plane, so one of its coordinates defining that plane remains the same. For example, if it is rotating in the x,y plane, then the z coordinate remains a constant, i.e., z=k, defining the rotation plane.
etc.
