Given information
Given the term a geodesic and asked its definition along with its role in General Relativity.
Step-by-step explanation
Step 1.
Geodesics helps in generalising the concept of a straight line of classical mechanics to general relativity’s curved space-time. The path followed by the non-accelerating particles is a geodesic. This path will be a length minimizing curve. In the sphere this path is circular and in the plane, it is a straight line.
