The “Motion” chapter from the UP Board Class 9 Science Book introduces students to one of the most important concepts in physics — the study of objects in movement. Based on the latest NCERT syllabus, this chapter explains the difference between distance and displacement, speed and velocity, and helps students understand how to describe motion mathematically.
Students learn about uniform and non-uniform motion, acceleration, and graphical representation of motion using distance-time and velocity-time graphs. These concepts are supported by examples and real-life applications, such as the motion of vehicles, falling objects, and running athletes.
The chapter also includes important formulas and numerical problems that help students develop problem-solving and analytical skills. Activities and illustrations make it easier to visualize motion and its parameters in practical situations.
The UP Board Class 9 Science Book – Motion provides clear explanations, solved examples, and NCERT-based exercises that ensure conceptual clarity. This chapter forms the foundation for advanced topics in physics and helps students perform well in exams and future studies.
