NCERT Solutions for Class 9 Science Chapter 8 Motion NCERT Solutions for Class 9 Science (physics) Chapter 8 Motion are given below. In these solutions, we have answered all the intext and exercise questions provided in NCERT class 9 science textbook. Class 9 Science Chapter 8 Textbook Questions and Answers INTEXT QUESTIONS PAGE NO. 100 Question 1: An object has moved through a distance. Can it have zero displacement? If yes, support your answer with an example. Answer: Yes, zero displacement is possible if an object has moved through a distance. Suppose a body is moving in a circular path and starts moving from point A and it returns back at same point A after completing one revolution, then the distance will be equal to its circumference while displacement will be zero. Question 2: A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position? Answer: Given, side of the square field = 10 m Therefore, perimeter = 10 m × 4 = 40 m Farmer moves along the boundary in 40 second Time = 2 minutes 20 second = 2 × 60 + 20 = 140 s Since, in 40 second farmer moves 40 m Therefore, in 1 second distance covered by farmer = 40 ÷ 40 = 1m. Therefore, in 140 second distance covered by farmer = 1 × 140 m = 140 m Thus, after 2 minute 20 second the displacement of farmer will be equal to 14.1 m north east from initial position. Question 3: Which of the following is...
