Master Class 8 Science with Sarthaks' Notes!

Science in Class 8 isn’t just a subject—it’s a whole new way to understand the world around you. From figuring out how cars move to why some things catch fire while others don’t, Class 8 Science is filled with fascinating concepts. Sarthaks' free and comprehensive notes are here to make everything crystal clear for you. Let’s dive into some of the key topics that will blow your mind!

1. What is Friction Class 8?

Ever wondered why you can walk without slipping? Or why your bicycle comes to a stop when you hit the brakes? That’s friction at work! Friction is the force that resists motion between two surfaces in contact.

  • Everyday Superhero: Whether it's stopping your car or helping you light a matchstick, friction is essential in daily life.
  • Different Types: Static friction, sliding friction, rolling friction—all of these have unique roles in making our world function smoothly.

Sarthaks’ notes on what is friction Class 8 break down the concept with real-world examples and diagrams to help you understand why this invisible force is such a big deal.

2. Force and Pressure Class 8 Notes

Force and pressure may sound like serious science stuff, but they’re everywhere—from the way you open a door to the pressure you feel while swimming underwater.

  • Force Basics: A push or a pull—simple, right? But did you know forces can change the shape, speed, or direction of an object?
  • Pressure Power: Pressure is force acting on a unit area, and it explains everything from why sharp knives cut better to why deep-sea creatures look so strange.

Sarthaks’ Force and Pressure Class 8 Notes will help you master these concepts with ease and show you how they’re used in real life. Physics will never feel boring again!

3. What is Combustion Class 8?

What happens when you burn wood or light a candle? That’s combustion—a chemical process where a substance reacts with oxygen to release energy in the form of heat and light.

  • Everyday Combustion: From burning fuel in cars to the gas stoves in your kitchen, combustion is everywhere.
  • Types of Combustion: There’s rapid combustion, spontaneous combustion, and even explosion (the exciting kind used in fireworks!).

With Sarthaks’ notes on what is combustion Class 8, you’ll get to explore this fiery topic in detail—without any risk of getting burned!

4. Coal and Petroleum Class 8

Ever stopped to think about what powers your car, electricity, or even that cozy fireplace? The answer lies in fossil fuels like coal and petroleum, which are formed over millions of years.

  • Coal: This black rock is more than just fuel—it’s also used in making steel and electricity.
  • Petroleum: Known as "liquid gold," petroleum gives us everything from petrol and diesel to plastics and chemicals.
  • Why It Matters: Fossil fuels are non-renewable, which means once they’re gone, they’re gone for good. That’s why learning about them is so important.

With Sarthaks’ Coal and Petroleum Class 8 notes, you’ll not only understand these fuels better but also learn why it’s crucial to conserve them for the future.
