Certainly! Here are some key points on Class 8 Chapter 9 - Force and Pressure:
1. **Force Definition:**
- Force is a push or pull acting on an object, causing a change in its state of motion.
2. **Types of Forces:**
- Contact Forces: Applied by direct physical contact (e.g., pushing, pulling).
- Non-Contact Forces: Act from a distance (e.g., gravity, magnetism).
3. **Effects of Force:**
- Changes in shape, size, or motion of an object.
4. **Measuring Force:**
- Unit of force is Newton (N).
- Force is a vector quantity with both magnitude and direction.
5. **Pressure:**
- Pressure is the force acting per unit area.
- Formula: Pressure = Force / Area.
6. **Factors Affecting Pressure:**
- Increasing force increases pressure.
- Increasing area decreases pressure.
7. **Units of Pressure:**
- Pascal (Pa) is the standard unit of pressure.
8. **Applications of Pressure:**
- Hydraulic systems use pressure to transmit force (e.g., brakes in cars).
9. **Atmospheric Pressure:**
- Pressure exerted by the air surrounding us.
- Standard atmospheric pressure is about 101.3 kPa at sea level.
10. **Balanced and Unbalanced Forces:**
- Balanced forces do not cause a change in motion.
- Unbalanced forces lead to acceleration or deceleration.
Remember to go through your textbook and class notes for detailed explanations and examples. Good luck with your studies! 📚

Heyyy sir
Aap kya kamal padhate hai aaram se samjh jate hai thanks for teach is ☺😊😇
👑Important points👑
Please! Always remember this points
1. Force = m*a
2. Pressure = Force/Area
3. SI unit of force = Newton
4. Symbol= N
5. Atmospheric pressure reduces as height above sea level increases.
6. Liquid pressure is measured by ' MANOMETER '.
7. PW is best😊
8.🙏🙏🙏
🙏
Air pressure measured by ( BAROMETER)
Yes you are right👍🏻
Sirr really mujhe ye numerical nahi samjh aa rahe the but aapne samkha diya to abb samjh me aa gaya thank you sir kal exam tha ❤❤
Bhai acche se exam dena.

Bhai mass aur weight mein kya difference hai
@@varunabhalla4394 Mass is the actual content present in a body and weight is force applied by earth on a body
@@varunabhalla4394 Mass is the measure of the amount of matter in a body. Mass is denoted using m or M. Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity. Weight usually is denoted by W.
