a ray
displacement
You are probably referring to a line, ray, or a line segment.Each of these figures are straight and are one-dimensional (or 1D).A line goes forever in both directions, and looks like an arrow pointing in 2 opposite directions.A ray goes forever in one direction. It has an arrow pointing in one direction, and in the opposite direction there is a dot, or point, that marks the endpoint.A line segment has two points on either side and does notgo on forever.
A line that goes on forever in both directions is a line. One that starts at one point and continues forever in the other direction is a ray, and one that has two definite ends is a line segment.
Such a figure cannot exist. If it goes on forever in only one direction then it must have an end point.
circle
it is called a ray
a straight line that extends for a point forever in one direction
If you are talking about line segment-type objects, it would be a ray.
If you mean a straight path, rather than a strait path, then it is a ray.
a line a ray goes in only one direction forever No, a line goes on forever in two directions, a ray starts at one point and then goes on forever.
A ray is a straight line that starts at a point and extends infinitely in one direction. It has a defined endpoint but continues on forever in the direction it points. A ray can be represented with an arrow pointing in the direction of its extension.
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
displacement
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
Stand straight. Now point straight up. Point straight ahead. Point straight to your left. Now point in a direction at right angles with all three previous directions: there's your extra dimension.
It could be a displacement vector.
