Answer 2

The shortest curve joining two fixed points on a given surface and lying entirely on that surface is called a geodesic.

• In geometry, a geodesic is regularly a curve addressing in some sense the shortest way (circular segment) between two places in a surface, or all the more for the most part in a Riemannian complex.
• It is ordinarily a curve addressing in some sense the shortest way between two places in a surface, or all the more for the most part in a Riemannian complex.
• The term additionally has significance in any differentiable complex with an association.
• In general relativity, a geodesic generalizes the thought of a "straight line" to curved spacetime.
• Critically, the world line of a particle liberated from all outside, non-gravitational powers is a particular kind of geodesic.
• At the end of the day, and unreservedly moving or falling particle generally moves along a geodesic.
