The motion represented by a horizontal line on a distance time graph?

Answer 1

It represents that the object is remaining at a fixed distance. Typically that means it is not moving.
Motion in a horizontal line by distance can be shown on a graph. This is what tells the Y-axis.

Answer 2

With distance as the X coordinate, the graph is meaningless, since it implies that the object is at many locations in the same instant of time. With time as the X coordinate, it means that the object is not moving from the point of view of an observer in the object's reference frame, or at least it was not moving over the time span represented by the horizontal line.

Answer 3

A line that curves up or curves down on a distance/time graph is always a sign

of accelerated motion. But you can't necessarily always spot the presence of

acceleration on that graph.

Acceleration is any change in speed or direction of motion. On a circular track, for

example, speed may be constant, but the constantly-changing direction indicates

constant acceleration. However, since the speed is constant, the distance/time

graph is a sloped, straight line ... the same as it would be for un-accelerated motion

at a constant speed in a straight line.

Answer 4

on a distance time graph, the slope of the line represents the speed of the object. A horizontal line indicates no movement. The object is at rest.

Answer 5

It usually means that the object is staying the same height, speed, etc.

Answer 6

constant velocity i suppose....:)
