Question

If speed - time graph of an object is a straight line parallel to the time axis then what will you say about its motion :
Option hai
a) object is showing uniform acceleration
b) object is at rest
c) object is showing non - uniform
acceleration
d) object's acceleration is zero ​

Answer 1

Answer:

(d) The object's acceleration is zero.

Explanation:

Since it is a speed-time graph, the slope will give you the acceleration of the body in motion. And as the graph is a straight line parallel to the time-axis, you can easily infer that it's slope or acceleration is zero.

However, if it had been a distance-time graph, the straight line parallel to time axis would mean that the object is at rest.

I hope I have got my point across :)

Answer 2

Explanation:

b) object is at rest.
