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! 📚

Effects of force 1. It's changes the shape and size of an object. 2. It can move the object which is in rest. 3. It can stop the object which is moving . 4. It can make faster moving objects more faster. 5. It can make slower moving object more slower.
