Question

If the distance-time graph of the motion of an object is a straight line parallel to the time axis, what will we infer

1. Object is moving with constant speed

2. Speed of object is accelerating

3. Object is at rest

4. Speed of the object is slowing down

​

Answer 1

Answer:

3. object is at rest

if line is parallel to time axis then distance is constant.

the object stays at a specific point for a long time which means it is at rest.

Answer 2

Answer:

3. Object is at rest, because the distance is constant but the time is increasing
