DISTANCE/DISPLACEMENT TIME GRAPH
A graph drawn with time along x-axis and distance along y-axis is called as distance/displacement-time graph. As shown below
Slop of Displacement time graph
Slop of displacement time graph of a body in motion gives velocity of that body.
To find slop of graph draw a triangle ΔABC in inclined line of graph. Then
Slop = AB/BC
Here AB is displacement and BC is the time
Slop = displacement/time = velocity
So the slop of displacement time graph gives velocity. Similarly slop of distance time graph gives speed.
