Distance.
The shortest distance between any two points is called displacement.
The shortest distance between four points is a straight line to and from each individual point. If all four points are aligned, the result will be a single straight line through all four points.
Multiple straight lines.
The two points and the centre of the earth define a plane, and the intersection of this plane with the surface of the earth is a circle - the "Great Circle". The shortest distance between the two points is the smaller of the two arcs on this circle.
The shortest distance between two points is a line, or a line segment. If you have two points, and you know they are part of a line, you can connect them with a line.
displacement is the vector quantity and the distance is scalar quantity, displacement is the shortest distance between two points.
There is a big difference between Scalar and vector quantity. Vector quantity means something where direction is not important.eg- Displacement(the shortest distance between the displacement points of an object). whereas in scalar quantity Direction is important. eg. Speed
The shortest distance between any two points is called displacement.
A Straight Line is always the shortest distance between two points.
In plane geometry, the shortest distance between two points is a line. In spherical geometry, the shortest distance between two points is a segment of a great circle. The distance between one point and another is known as the displacement.
The shortest distance between four points is a straight line to and from each individual point. If all four points are aligned, the result will be a single straight line through all four points.
The shortest route between two points on the surface of a planet, when routes are limited to the planet's surface, is the arc of the great circle that connects the two points. The shortest route between two points anywhere, without regard to intervening matter or energy preventing the route from being followed, is always the line connecting the two points.
