Question

velocity-time graph for the motion of an object in a straight path is a straight line parallel to the time axis?
1.identify the nature of motion of the body.
2.find the acceleration of the body.
3.draw the shape of distance-time graph for this type of motion.

Answer 1

accord to graph velocity is constant
1. obj with constant velocity
2.a=0 
3.a straight line graph with fixed slope

Answer 2

1. the body is in uniform rectilinear motion

2. the acceleration of the body is zero , as the graph is parallel to the x axis which means the slope of the graph is zero. The slope of a v-t graph gives the acceleration and as here the slope is zero so acceleration is zero too.

3. ( refer to the picture above........)
