What is Included in the Eduinput Class 9 Physics Chapter 4 New Notes (New Syllabus 2025-26)?

These physics new notes for class 9 chapter 4 cover every topic that students find confusing or commonly lose marks on in the Punjab Board exams.

Here is a complete topic-by-topic breakdown of what this new guide covers, from parallel forces to centripetal force:

• Like and Unlike Parallel Forces—explains the difference between parallel forces acting in the same and opposite directions with clear examples
• Turning Effects of Force and Moments—teaches how to calculate the moment of a force using force × perpendicular distance and apply it to real-life problems
• Centre of Mass and Centre of Gravity—explains what both terms mean and how to find the centre of gravity of a plane lamina using a plumb line
• States and Conditions of Equilibrium—covers stable, unstable, and neutral equilibrium with daily life examples and the conditions required for each
• Stability and Centre of Gravity—explains how the position of the centre of gravity affects the stability of objects and how to improve stability by lowering the centre of mass and increasing the base area
• Real-Life Applications of Stability—covers how stability physics is used in engineering, balancing toys, racing cars, and other everyday examples
• Rotational Motion and Resultant Moment—explains how rotating objects continue to spin unless acted upon by a resultant moment, similar to Newton’s first law for translational motion
• Centripetal Force and Circular Motion—explains how objects move in a circular path due to centripetal force, with real-life sources such as string tension and gravity
