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.

Answer: (3) Muscular force is the force produced by the use of muscles. Muscular force occurs as a result of contraction of the muscle which
