Question

1. The displacement-time graph of a
moving object is a straight line. Then,

(a) its acceleration may be uniform
(b) its velocity may be uniform
(c) its acceleration may be variable
(d) both its velocity and acceleration may
be uniform​

Answer 1

Answer:

d) both it's velocity and acceleration may be uniform

Answer 2

Velocity may be uniform.

• As per the question, the displacement-time graph of a moving object is a straight line.

• Now, straight line can be either a line parallel to Time Axis or can be at a slope.

• When the line is parallel to the Time Axis, we can say that the displacement of the object is not changing with time and hence the object is stationary.

• However, if the line is is having a slope, it means that the displacement is changing uniformly due to presence of a constant velocity. So, velocity is uniform.
