Graphs[S-T, V-T, A-T]

Displacement-time graphs:
These graphs are down by ploting displacement on Y-axis and time on X-axis .Slope of this graph gives velocity
a)If the graph is a straight line parallel to time axis,then body is at rest.Body has some intial displacement S_o
b)If the graph is a straight line with a positive slope,then the body is moving with constant velocity.Graph(1) represents that body has zero initial displacement and graph(2) represents that body has intial displacement S_o.
              
                            
c)If the graph is a parabola or with a slope which increases at a steady rate,then body is moving with uniform acceleration.In case (1) body has no intial displacement and in case (2) body has  intial displacement S_o .
                   
                                                                                                                                        
d) If the graph is a parabola or with a slope which decreases at a steady rate,then body is moving with uniform retardation.
                    

e)For a body projected vertically up,this graph is a parabola as shown
                  

f)If  the graph is a straight line with negative slope as shown,than body is approaching the observer with  constant velocity.
                

g)These two graphs are impossible
