Class 9 Science Chapter 6 Notes with Assignment and Test is a complete NCERT-based study bundle for How Forces Affect Motion. The chapter focuses on force, friction, balanced and unbalanced forces, Newton’s laws of motion and their applications in everyday life. The material is based on the latest NCERT Exploration Book. 
What’s Included
1. Class 9 Science Chapter 6 Notes PDF
Detailed notes covering the concept of force, measurement of force using a spring balance, balanced and unbalanced forces, net force, friction, Newton’s First, Second and Third Laws of Motion, acceleration, mass, weight, momentum and real-life applications. 
The notes also include investigations on friction using different surfaces and a spring balance, along with applications such as airbags, catching a cricket ball, walking, rocket launches and friction in everyday life. 
2. Chapter 6 Assignment PDF
Practice material containing MCQs, True/False, Fill in the Blanks, Assertion-Reason and Easy, Medium & Hard subjective questions. 
The assignment includes numerical problems on net force, acceleration, braking force, friction, connected blocks and rocket thrust. 
3. Chapter 6 Science Test PDF
A 40-mark, 1-hour chapter test covering MCQs, Fill in the Blanks, True/False, Assertion-Reason and subjective questions.
