Velocity - Time Graphs.
A velocity - time graph
shows
how an objects velocity (how fast it
is moving) changes with time.
The above graph shows
that the objects velocity does
not change as time goes by.
It is constant
velocity.
Compare this with the distance -
time graph for constant velocity.
The above graph shows
that the objects velocity is
increasing as time goes by.
This is acceleration.
The straight line shows that it is
constant acceleration.
The slope of the line shows
(i) the acceleration is positive because the
line slopes
upwards
(ii) how fast the acceleration is.
