Graphs for Motion -

1) Distance-time graphs (s-t graphs)

a) When the object is stationary or at rest -

The distance time graph for stationary object is the line parallel to time axis. b) When object is in uniform motion -

The distance time graph for the object moving in uniform motion is the straight line inclined to time axis. C) When object is in non-uniform motion -

The distance time graph for object moving in non -uniform motion is the curved line. Important results of distance time graphs -

1) area under curve of s-t graph = displacement/distance travelled by the object

2) slope of s-t graph = velocity of the object

Velocity time graphs (v-t graphs)

a) When object is moving with constant speed -

The velocity time graph for an object moving with constant/same speed is given by a straight line parallel to time axis. b) When object is in uniform motion -

The velocity tiem graph for an object in uniform motion is the straight line inclined to time axis. C) When object is in non-uniform motion -

The distance time graph for object moving in non -uniform motion is the curved line. Important results of velocity time graphs -

1) area under curve of v-t graph = displacement/distance travelled by the object

2) slope of v-t graph = acceleration of the object
