Activity 9.3 Class 9 Science Chapter 9 Force and Laws of Motion Solution

Activity 9.3 Class 9 Science Chapter 9 Force and Laws of Motion

Activity 9.3 Class 9 Science belongs to Chapter 9 Force and Laws of Motion   Class 9 Science. You will get a complete solution with an explanation and a conclusion. After reading activity 9.3, you will be able to answer the questions based on the activity.


Activity 9.3 Class 9 Science Chapter 9

 

You are suggested to study NCERT activity 9.3 class 9 science chapter 9 explanation with a conclusion so that you can attempt questions based on the activity 9.3 class 9 science.


Activity 9.3 Class 9 Science

   ·     Place a water-filled tumbler on a tray.

   ·     Hold the tray and turn around as fast as you can.

   ·     We observe that the water spills, why?

 

Observation Activity 9.3 Class 9 Science


Water in the tumbler spills when we turn around the tray.


Explanation Activity 9.3 Class 9 Science


When we turn around the tray, it creates a force on the tumbler as well, so the glass also moves around. but water in the tumbler tends to remain in the rest position due to the inertia of rest. So water spills out.


This happens because frictional force is produced between the tray surface and the surface of the tumbler, so the tumbler moves. But the frictional force between the tumbler and the water is less or absent, that’s why there is no movement in the water. Water tends to remain in the rest position and spills out.


Conclusion Activity 9.3 Class 9 Science


This activity also explains the Law of inertia as activities 9.1 and 9.1 does.
