Question

Discuss the graphical representation of linear motion and its type with examples

Answer 1

A graph is a pictorial representation of the relation between two sets of data of which one set is of dependent variables and the other set is of independent variables.To describe the motion of an object, we can use line graphs. In this case, line graphs show dependence of one physical quantity, such as distance or velocity, on another quantity, such as time.

Answer 2

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.
