Answer:
The
slope of distance-time graph of a uniformly accelerated motion in one dimension
represents the instantaneous velocity. The slope of distance-time graph of a
uniform motion in one dimension represents the uniform velocity of the moving
body.
The slope of velocity-time graph of uniformly accelerated
motion at a given instant represents the acceleration of the moving body at
that given instant.
For the distance time graph of an accelerated motion, the
positive value of slope represents that the velocity of the moving body is
increasing with time and the negative value of slope represents that the
velocity of the moving body is decreasing with time.
Similarly for the velocity-time graph of a uniformly
accelerated motion, the positive value of slope represents that the acceleration
is positive i.e. the body is accelerated and negative value of slope represents
that the acceleration of body is negative i.e. the body is retarded.
