The slope of the line on a position-time graph reveals information about an object's velocity. What conclusion can you draw regarding the motion of an object, if the graph is a
$(i)$ Horizontal line.
$(ii)$ Straight diagonal line.
$(iii)$ Curved line.
$(i)$ Object is at rest.
$(ii)$ Object is moving with uniform speed.
$(iii)$ Object is moving with non$-$uniform speed.
Area under velocity$-$time graph is equal to the
A body can have zero average velocity but not zero average speed. Justify.
What is the average velocity of a particle when it returns to the starting point ? Can its average speed be zero ?
The velocity-time graph (Fig.) shows the motion of a cyclist. Find $(i)$ its acceleration $(ii)$ its velocity and $(iii)$ the distance covered by the cyclist in $15\,\sec $.
What conclusion can you draw from the displacement$-$time graph of a body shown below ?
