In cases like projectile motion, although the acceleration vector is constant (ignoring air resistance), a single coordinate axis fails to describe the motion of the particle, since it occurs in a plane; therefore we need a minimum of two coordinate axes to fully describe the trajectory of that particle. I was wondering, is there a case of constant acceleration where two axes would be insufficient to describe the trajectory (forcing us to use a three dimensional coordinate system)?
