Physics Questions

Physics is one of the branches of Science and also the most fundamental scientific disciplines. Physics helps in understanding everyday activities such as answering questions like why the sky is blue, what makes us walk easily on roads, why is it important to have a moon, etc.

From the above-mentioned examples, it becomes clear that Physics concentrates in explaining the behaviour of the universe, force, and matter and their effects. Physics has helped in developing new technologies and in many inventions.

Physics as a subject is further divided into branches which include Modern Physics, Classical mechanics, Astrophysics, Nuclear Physics, Electromagnetism, and Optics. These branches are further divided into sub-topics and most of these topics are covered in school syllabus. 

Class 11 includes concepts like Units and measurements, Kinematics, Gravitation, Oscillation and Waves, Thermodynamics, Laws of Motion, Work, Power, Energy, and Particle movement. 

Class 12 includes concepts such as Magnetism, Electromagnetism, Optics, Current electricity, Electrostatics, Dual nature of radiation, and Electronic devices. 

We know that all these concepts have major questions that are covered in textbooks which are either descriptive or problematic. Here, at BYJU’S students will find questions that are descriptive as well as concept based. Questions explained here includes examples, properties, principles, types, and definitions.

The colour of the sky during day-time is blue because the molecules in the air scatter blue light more than the red light because the wavelength
Following are the difference between short circuit and overload:(a) Short circuit occurs when there is a fault between the line to earth while
Red colour is used for stopping vehicles because it has a longer wavelength. As the wavelength is longer, the scattering of light will be less
Given, Resistance = 2 Ohm Current = 0.4 Ampere Voltage = 4V According to Ohm's law, V = I x R Therefore, \(R=frac{V}{I}\)
Consider the solutions to be A and B respectivelyLet X litres of A be mixed with Y litres of BGiven that, X + Y = 21 (equ.1)Quantity of acid
Rancidity is defined as a state of food in which the food becomes undesirable. Most of the times rancidity is used for explaining the oxygen
Given, The image formed is in front of a concave mirror which is real. Therefore, magnification is negative. m = -3 u = -10cm m = Solving
When a rubber band is stretched, the force acting on the rubber band is known as the elastic force. When a material is stretched and returned
