A horizontal line on a distance-time graph indicates ________.
Answers
Answer:
i hope you help...
Explanation:
A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!

- What is a Distance-Time Graph?
A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph.
Distance is plotted on the Y-axis.
Time is plotted on the X-axis.
Note: Curved lines on a distance-time graph indicate that the speed is changing.

Importance of Distance-Time Graph
We deal with the distance-time graph while studying the motion of bodies. If we record distance and time for the motion of a body and plot the same data on a rectangular graph, we will obtain a distance-time graph corresponding to the motion of that body.
Example:
For better understanding, let us consider an example of uniform motion. A bus driver drives at a constant speed which is indicated by the speedometer and the driver measures the time taken by the bus for every kilometre. The driver notices that the bus travels 1 kilometre in every 2 minutes.
- As can be inference by the graph we have a parabola passing through origin hence equation of motion is y=kt
2
its velocity is v=
dt
dy
=2kt
acceleration=a=
dt
dv
=2k
hence acceleration of object is constant and uniform throughout the motion
