Question

On a displacement-time graph, a horizontal straight
line corresponds to motion at :​

Answer 1

Answer:

On a distance time graph, a horizontal straight line corresponds to motion at zero speed constant speed increasing speed decreasing speed.

Answer 2

Answer:

MOTION AT REST

Step-by-step explanation:

Let DISPLACEMENT(S) be on Y-axis

and Time(t) on X axis.

Then a horizontal line on the graph represents that the SLOPE( $\frac{dS}{dt}$)or velocity   is equal to ZERO.

Hence, the horizontal straight line on displacement time graph represents the motion of a particle at rest.
