MOTION, CBSE CLASS IX, PHYSICS NOTES PART II
CBSE CLASS 12, MOTION, PHYSICS NOTES- (PART II) MOTION According to the CBSE Syllabus 2025-26 CBSE Class 9 Science Chapter 8 Motion Notes In Class 9 Science Chapter 8 Motion, students learn to describe the motion of objects along a straight line and express such motions through simple equations and graphs. The chapter also discusses ways of describing circular motion. TOPICS IN THE CHAPTER • Introduction • Distance and Displacement • Uniform and Non-uniform motion • Speed • Velocity • Accelerated and Decelerated motion • Equations of motion • Graphical representation of motion • Uniform circular motion SPEED The measurement of distance travelled by a body per unit time is called speed. • If a body is executing uniform motion, then it will be at a constant speed or uniform motion. If a body covers a certain distance in a certain amount of time, its speed is given by, Speed=Distance / Time Speed (v) = Distance Travelled / Time Taken = s / t ...
