Question

what can you say about the motion of an subject if it speed time graph is a straight line parellel to the time axis
​

Answer 1

Here , the following condition is given -

speed time graph is a straight line parellel to the time axis

Now , in the speed time graphs , we know -

The x axis represents time and the y axis represents speed .

Here , the graph is parallel to the x axis -

this means that speed does not change with respect to time .

So , this means that the body is at rest in that respective time interval .

Conclusion -

When the speed time graph of a body is a straight line parellel to the time axis , it means that the body is at rest with respect to time .
