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.
Displacement is distance combined with direction. It gives the straight-line distance and the direction from the starting point to the ending point of an object's motion.
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.
