This page gives detailed information on CBSE Class 12 Physics Syllabus 2023-24 which can be referred for Class 12 CBSE Board Examination. As per the revised Class 12 Physics Syllabus, the theoretical part will include 70 marks and the evaluation scheme will be 30 marks. There are no chapters that have been newly added or exempted from the existing syllabus. As stated by the Central Board Of Secondary Education, the new syllabus will be similar to the CBSE Class 12 Physics 2022 - 23 Syllabus. The CBSE Board has released the revised Syllabus For Class 12 Physics for the academic session 2023-24. Study of physics helps students to develop their quantitative reasoning and problem- solving skills and prepare them for a world of technology. This difference of pressure is helpful in giving a vertical lift to the plane.Physics is one of the most important and fundamental branches of science. Consequently the pressure above the surface of the wing is less as compared to the lower surface of the wing. Due to this shape of the wing, the air currents at the top have a large velocity than at the bottom.
The upper surface is made convex and the lower surface is made concave. Wings of Aeroplane Wings of an aeroplane are made tapering. Bernoulli’s principle is used in an atomiser and filter pump. It is used in a carburettor to mix air and petrol vapour in an internal combustion engine.
Venturimeter, atomiser and filter pump Bernoulli’s principle is used in venturimeter to find the rate of flow of a liquid. Many people find this situation paradoxical when they first encounter it (higher velocity, lower pressure). Bernoulli's law states that if a non-viscous fluid is flowing along a pipe of varying cross section, then the pressure is lower at constrictions where the velocity is higher, and the pressure is higher where the pipe opens out and the fluid stagnate.
