Precisely that, a straight line, unless you are talking about vectors, though they have magnitude & direction. For a line that is not a vector you've given no information on which to base a proper answer.
If the line is generated by a linear equation & its ends are set by co-ordinates:
its length is
Square-root [ (dX)^2 + (dY)^2 ]
by Pythagoras, where the "d" means the change in the X and Y values.
Its direction then may be described by its angle A with the X-axis by basic trig:
Tan A = dY/dX.
Its gradient is dY/dX (function)
Displacement includes the distance between the starting and ending points and the direction in which you travel.
displacement
It could be a displacement vector.
The best shape would be a segment. because it describes a straight li e but not never-ending
Ray - A ray is part of a line that has one endpoint. It continues in one direction without ending.
The volume or weight of a fluid displaced by a floating body (as a ship) of equal weight
Distance is the total length of the path traveled, while displacement is the change in position from the starting point to the ending point in a straight line. Distance is a scalar quantity, indicating magnitude only, while displacement is a vector quantity, indicating both magnitude and direction.
a road......?
Displacement includes the distance between the starting and ending points and the direction in which you travel.
hi
A vector.
A vector.
A never-ending straight path that goes in one direction is called a line. Euclid, the Greek mathematician, described it as "breathless length".
It is called a line segement
displacement
In the given examples, distance is a scalar quantity that represents the total length of the path traveled, regardless of direction. Displacement, on the other hand, is a vector quantity that represents the change in position from the starting point to the ending point, including direction. Distance can be greater than displacement if the path is not a straight line.
The distance and direction between starting and stopping positions is displacement.
