Final answer:
In physics, a plane can be created on a non-planar surface by using mathematical equations to define the plane or by approximating the non-planar surface as a collection of small, flat planes.
Step-by-step explanation:
In physics, a plane can be created on a non-planar surface by using mathematical equations to define the plane. By identifying a set of points on the surface that lie in the same plane, the equation of the plane can be determined. For example, if we have three non-collinear points on the non-planar surface, we can use them to define a plane. Additionally, if the non-planar surface is smooth and continuous, it can be approximated by dividing it into small patches that can be treated as locally flat planes.
