Velocity - Time Graphs.
You may be shown a graph like the
one below
and be asked to describe the
motion of the object.
In region A the object is moving with constant acceleration.
In region B the object is moving with constant velocity.
In region C the object is again
moving with constant acceleration
but compared with region A
(i) the acceleration is
slower because the slope is less steep
(ii) the acceleration is
negative
because the slope is downwards.
The total distance
travelled by the object can be calculated
by measuring the area
under the graph.
