Question

what is radial path?

Answer 1

Hey there !

For any given initial position and trajectory we can generate the subsequent geodesic path in terms of r as a function of t. ... A plot of this r versus t corresponds to the position of a point on the rim of a rolling wheel of radius R/2, where a is the angle of the wheel.

Hope it helps you !

Answer 2

Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path. Tangential – intersecting a curve at a point and parallel to the curve at that point
