displacement
The direction and distance from the starting point to the ending point is referred to as "displacement." Displacement is a vector quantity that accounts for both the shortest straight-line distance between two points and the direction of that line. It differs from distance, which measures the total path traveled regardless of direction.
It could be a displacement vector.
Displacement includes the distance between the starting and ending points and the direction in which you travel.
A straight path that has a beginning but no end represents a ray in geometry. A ray starts at a specific point (the beginning) and extends infinitely in one direction. The angle associated with a ray is typically measured from the starting point to another point along the ray, but it can be described as having an angle of 0 degrees relative to its own direction.
The starting AND ending of your periods. :)

It could be a displacement vector.
The distance and direction between starting and stopping positions is displacement.
Displacement includes the distance between the starting and ending points and the direction in which you travel.
displacement
The volume or weight of a fluid displaced by a floating body (as a ship) of equal weight
The displacement of a lap is the change in position from the starting point to the ending point. It is a vector quantity, meaning it has both magnitude and direction. It can be calculated by finding the straight-line distance between the start and end points of the lap.
a road......?
I would need more information to provide a direction from the starting point to the ending point. Factors such as compass directions, landmarks, or a map would be helpful in determining the direction.
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
