Force and Pressure- Blog 8

CLASS 8 CHAPTER 11
Force and Pressure
Day 8

"Always Question, Always Wonder" 

Dear Learners,
Thank you for logging in! You're wonderful!😊 

 At the end of this class, you will be able to:
1. Define atmospheric Pressure.
2. Explain Pressure exerted by gasses through various activities.
3. Explain the role of a barometer.
4. State different types of a barometer.

Happy Learning!😊

Pressure exerted by Gases:

The pressure exerted by the air at any point on the earth is called Atmospheric Pressure at that point.

Atmospheric Pressure decreases with altitude.

CLASS 8 CHAPTER 11 Force and Pressure Day 4 "Always Question, Always Wonder "  Dear Learners, Thank you for logging in! You're wonderful!😊   At the end of this class, you will be able to: 1. Distinguish between Balanced and Unbalanced forces. 2. State the effects caused by force. Happy Learning!😊 Balanced and unbalanced Forces: https://youtu.be/-Rjid6hQuww  ( Check this video on Balanced and Unbalanced Forces) Effects of Force: Force acting on a body may cause the following effects on it: 1. A force acting on a body can change its state of motion or rest. 2. A force can the direction of motion of a moving object. 3. A force can change the shape and size of an object. 4. a force can stop a moving object. 5. A force can change the speed of a moving object. https://youtu.be/QuFh8GYDf7A?t=17  (check this video on effects of force) Drill: 1.       1. .   What will be the net force acting on a body if 2 forc

F & P Day 3 Drill In today's class,  we will revise what we have learned so far: The blog has some questions you will answer. You may use the previous blogs to answer them. You will write the answers in the comment section with your name. You should also keep them safe in your science note book. Drill: 1.   Two boys pull a rope from two ends with a force equal to 100N each. What is the resultant force? 2. A body is acted upon by two forces of 200N and 300N, in the same direction. What is the resultant force acting on it? 3. If several forces act on a body in different directions, in which direction will the body move? 4. What is the resultant force of the two forces F1 and F2 acting on a body in the opposite directions? 5. What is the S.I unit of force? 6. The force exerted by one object on another by virtue of their masses is__________. 7. A spring balance is used for measuring____________. 8. Application of
