CBSE Syllabus for Class 8 Physics 2021-2022 Exam

 

CBSE Class 8 Physics syllabus will help you identify the topics that you need to study for your Science exam. The Physics syllabus in Class 8 includes topics like force and pressure, friction, sound, the chemical effects of electric current, some natural phenomenon like lightning, light, and the stars and the solar system. Although the Science subject in Class 8 is not divided into different streams like Physics, Chemistry and Biology. But, you must understand which topics are covered in which category. This will help you form a solid base for every Science subject for higher classes. 

 

In Class 8 Physics, you will be studying what is force and how it can bring a change in the state of motion of an object. You will study why friction force is known to be a necessary evil, what is fluid friction and how can we increase or decrease friction. You will learn how sounds are produced by humans, how do we hear a sound with the help of our ears, and what is the difference between music and noise. Then, you will learn about the conduction of electricity and liquids can carry electricity with them. You will study the chemical effects of the electric current. 

 

Another unit of Class 8 Physics teaches the concept of light. For instance, how light makes things visible to us or how the rays of light get reflected from a surface. You will study the human eye to understand how we can see things with our eyes. CBSE Class 8 Physics syllabus also discusses some natural phenomena like lightning and earthquakes. You will learn how the exchange of charges takes place when lightning strikes. These concepts will help you understand how the concepts of Physics are applied in the natural world as well. Then, you will also learn about the solar system and the different members of the solar system like the Sun, the Moon, meteors, meteorites, asteroids, stars, satellites and the planets.
