CBSE CLASS 9TH SCIENCE(PHYSICS) CHAPTER MOTION (Graphical ) Part-2 GRAPH: A graph is a line, straight or curved which shows the variation of one quantity w.r.t other, which are interrelated with each other. y=f(x) In a relation of two quantities, the quantity which is made to alter at will, is called the independent variable. The other quantity which varies as a result of this change is called the dependent variable. Graph In any graph , the independent variable is represented along x-axis (Time). Dependent variable is represented along y-axis (Distance, Displacement, Speed , Velocity, Acceleration etc). TYPES OF GRAPHS: 1. When object is at Rest 2. When Object is in Uniform Motion 3. When Object is in Non Uniform Motion (Increasingly and decreasingly ) Types of Graphs in Motion Distance-Time Graphs: Distance time graph denoted by s-t graph shows the variation of distance covered by object taken on dependent axis with time independ
