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
