Bernoulli’s theorem states that the addition of all the energies of a fluid when fluid is in motion is constant. Or in other terms no energy is dissipated through friction between the layers of the fluid. This theorem is for ideal fluids.

Is there Numericals in physics class 11?
Ans: Yes, sample papers have all the important questions in physics class 11. Numericals are as important for physics as the theory questions.
How do you remember derivations in physics?
How do you practice derivations?
The best way to get command over derivations of physics is to understand it and practice the derivation periodically after sometime. Mathematics is the language of physics. If you are good at mathematics, then there is no difficulty in understanding the derivations of physics.
What is derivation of formula?
Derivatives are the fundamental tool used in calculus. The derivative measures the steepness of the graph of a given function at some particular point on the graph. Thus, the derivative is also measured as the slope.

How can I study physics?
- Make use of the preview that you did prior to the class. Again,
- Read the homework problems first.
- Read actively with questions in mind.
- Stop periodically and pointedly recall the material that you have.
- During your reading you will notice sections, equations, or ideas that.
What is the use of studying derivations?
To give an example, derivatives have various important applications in Mathematics such as to find the Rate of Change of a Quantity, to find the Approximation Value, to find the equation of Tangent and Normal to a Curve, and to find the Minimum and Maximum Values of algebraic expressions.

- Center of Mass and Conservation of Momentum.
Which chapter is easiest in Physics 11?
For PHYSICS : The easiest chapters among all the syllabus is the modern Physics, Radioactivity, kinematics( it is very scoring), Thermodynamics, waves and optics.
Is physics of 11 and 12 hard?
The physics of 12 the is very easier than the 11th. Because in 11th physics you need many concept in mechanics or waves. But in 12th physics you need only to learn the formula and you can easily solved the numerical.
Are derivations hard?
If you are good at mathematics, then there is no difficulty in understanding the derivations of physics. Simple tips for physics derivation: >>Understand the concept and terms to be used in the derivation.
What is the fastest way to memorize formulas?
- Grow your interest in the concept in which you are studying.
- Connect your concept with a visual memory.
- Knowing the process behind maths formulas.
- Always solve the problems with math formulas.
- Write down maths formulas.
- Stick your written formulas on your wall.
What is the derivation of kinetic energy?
The kinetic energy of a body is the energy that is possessed due to its motion. Kinetic energy is the work needed to accelerate an object of a given mass from rest to its stated velocity. The derivation of kinetic energy is one of the most common questions asked in the examination.
Are derivations important?
Derivations in physics are very important for CBSE class 12 board exams. Practicing them is necessary for getting good marks. It’s going to be a long answer. The following derivations are the most important from examination point of view.
What are the basic physics formulas?
- a = fracv-ut
- rho = fracmV
- P= fracWt
- P= fracFA
- E = frac12mv^2.
- f= fracVlambda
How do you read derivation?
One type of notation for derivatives is sometimes called prime notation. The function f ´( x ), which would be read “ f -prime of x ”, means the derivative of f ( x ) with respect to x . If we say y = f ( x ), then y ´ (read “ y -prime”) = f ´( x ).
How is Gauss law derived?
Derivation of Gauss’ law that applies only to a point charge The magnitude E of the electric field at a distance r from the charge +q is E = kq/r2. The constant k can be expressed as k = 1/(4 0), where 0 is the permittivity of free space.
Are derivations important for NEET?
Not all derivations are important but there are various derivations which you should practice so that you know how to start with questions basically numericals based on derivations like derivations of electrostatics are important and derivation of optics are also important it is because questions are moulded in such a …
What are the applications of Gauss theorem?
The applications of Gauss Law are mainly to find the electric field due to infinite symmetries such as: Uniformly charged Straight wire. Uniformly charged Infinite plate sheet. Uniformly charged thin spherical shell.
What is Pascal law class 11?
Pascal’s law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and the walls of the container. The pressure at any point in the fluid is equal in all directions.
What is Venturimeter 11?
Venturimeter is a flow measurement instrument. Here, a converging section of a pipe is used to increase the flow velocity and a corresponding pressure drop from which the flow rate of the fluid is deduced based on Bernoulli’s equation.
What is Stokes law in physics class 11?
Stoke’s Law states that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of the sphere, and the viscosity of the fluid.
What is the most famous equation in physics?
The equation E = Mc2 is perhaps the most famous equation of twentieth- century physics. It is a statement that mass and energy are two forms of the same thing, and that one can be converted into the other (ibid., p. 493).
