Welcome to the world of physics. With us, you can learn all the concepts of physics from class 7 - 12 in a very simplified way.

CBSE | NCERT | Class 9 | Physics | Chapter 8 | Motion - Topic - Graph

What is a graph? How many types of graph are there? why do we take a line graph for motion? how do you find the slope?

There are many types of graph. 
The pie chart is used to compare parts of a whole. Bar graphs are used to show a comparison among categories. The histogram is a bar graph that shows data in intervals. The line graph displays data that changes continuously over periods of time. In this chapter, you will focus on the line graph. On the x-axis of the line graph, you have an independent variable, and, on the y-axis, you have a dependent variable. 

(Independent variable) causes a change in (Dependent Variable) and it is not possible that (Dependent Variable) could cause a change in (Independent Variable).

Time is taken on the X-axis or the Y-axis? X-axis! Think why?
