This chapter deals with the study of the motion of objects along a straight line. It explains important concepts like distance, displacement, speed, velocity, and acceleration. Students learn how to represent motion using graphs and apply equations of motion to solve numerical problems. The chapter also introduces concepts of uniform and non-uniform motion and helps in understanding how objects move and change their position with time. Key Topics:• Distance and displacement• Speed and velocity• Acceleration• Types of motion• Graphical representation of motion• Equations of motion
