- What is unit of acceleration?
- What is zero uniform velocity motion?
- A body moving in a circle with constant speed. Is it having acceleration?
- A body goes from point A to B and then return then from B to A. what is the total displacement?
- Acceleration is a vector quantity True or false?
- What is the path of a velocity –time graph of a body moving with uniform acceleration
- What all ways the velocity of the body can be changed?
- What is average speed?

Class 9 Maths Class 9 Science

Given below are the links of some of the reference books for class 9 science.

These books by S.Chand Publications are detailed in their content and are must have books for class 9 students.- Science for Ninth Class Part1 Physics
- Science for Ninth Class Part2 Chemistry
- Science for Ninth Class Part3 Biology

- Oswaal CBSE Question Bank Class 9 Science Chapterwise & Topicwise We all know importance of practicing what we have studied. This book is perfect for practicing what you have learned and studied in the subject.
- Pearson Foundation Series (IIT-JEE/NEET) Physics, Chemistry, Maths & Biology for Class 9 (Main Books) | PCMB Combo These Foundation books would be helpful for students who want to prepare for JEE/NEET exams. Only buy them if you are up for some challenge and have time to study extra topics. These might be tough for you and you might need extra help in studying these books.
- Foundation Science Physics for Class - 9 by H.C. Verma This is one of my favorite Physics book for class 9. Most of the book is within the limits of CBSE syllabus. It might overwhelm you with its language but I feel if you can understand the content is authentic with plenty of problems to solve.

You can use above books for extra knowledge and practicing different questions.
