medium

Velocity$-$time graph for the motion of an object in a straight path is a straight line parallel to the time axis.

$(a)$ Identify the nature of motion of the body.

$(b)$ Find the acceleration of the body.

$(c)$ Draw the shape of distance-time graph for this type of motion.

Option A

Option B

Option C

Option D

Solution

$(a)$ If the speed $-$ time graph is a straight line parallel to the time axis, the object moves with a constant speed and the motion is uniform.

$(b)$ Since velocity is constant, therefore, acceleration is zero.

$(c)$ The distance-time graph is as shown
