Question

graphical representation of data
​

Answer 1

Answer:

Graphs are used to represent the relation between two physical quantities. When a body is at rest, the distance-time graph is a straight line parallel to time axis. When the body is.in uniform motion, the distance-time graph is a straight line inclined to time axis. The slope of a distance-

time graph gives speed, A velocity-time graph is a straight line parallel to time axis for a body moving with uniform velocity. When the velocity changes by equal amounts in equal intervals of time then the velocity-time graph is a straight line inclined to time axis. The slope of the velocity-time graph gives acceleration. When a body is moving with variable acceleration then the velocity-time graph is a curved line.
