Q 2: How to attempt a physics paper on the mainboard exam?
Ans: Firstly, make a note of all the formulas and revise them often to remember them by heart. Derivations play a key role in Physics. Learning the derivations of the Formulas will help you solve the questions on board with ease. Questions in the exam will be asked in a deviant way. To understand them you need to be very much perfect with the derivations of the formulas.
Always focus mainly on the topics with a high weightage of marks. Your main attention should be on concepts like a Sound wave, Wave Optics, Modern Physics, Alternating current. Thermodynamics is a subject which is common in both the subjects of Physics and Chemistry. This is also one of the most important topics in Physics. Thorough practice with all the concepts is a must.
Q 3: What will I learn in Fluid mechanics chapter?
Ans: In Fluid Mechanics chapter, you will be taught about Bernoulli’s Equation, Archimedes’ Principle, Pascal’s Law, Applications of Bernoulli’s Equation, the flow of fluids, incompressible and nonviscous fluid, atmospheric pressure and barometer and equation of continuity. The concept Some Mechanical Properties of Matter gives you a brief on Stokes’ Law, Hooke’s Law and the Modulus of Elasticity, Stokes’ Method, Poiseuille’s Equation, surface tension, the molecular structure of a material, critical velocity and Reynolds Number.
Q 4: What are the main concepts which I learn in the chapter Motion in 1 dimension?
Ans: Motion in 1 Dimension is the most important chapter of class 12 Physics. The chapter introduces you to the introduction to mechanics and kinematics, basic definitions, motion in one, two and three dimensions, uniformly accelerated motion, non - accelerated motion, graphs and relative motion uniformly.
This main focus of the chapter is on the moment of an object and how it changes its position with proportionate to the surrounding along with the time. Further, you will also learn about the types of linear motion like uniform linear motion and non-uniform linear motion, which includes vector quantities. These quantities are explained with linear momentum, acceleration, displacement, momentum, angular velocity, force, electric field and polarization.
