Every single function of our life is actually governed by some law or concept of physics. It is said that physics can actually explain everything from the beginning of the universe to life in the present. In class 11 students are introduced with some basic concepts and laws of physics. We will be covering important chapters such as units of measurements, motion in a plane and straight line, gravitational force, kinetic energy, etc.
Here students are introduced to the international system of units and its history. They will learn about concepts such as base units and derived units. There are also numerical problems regarding volume and surface area of objects.
This is the introduction of Kinetics. We will learn about rectilinear motion, reference points, path lengths, relative velocity, acceleration, and other such interesting concepts. There are also some basic mathematical problems for the students to practice.
Students will learn about the differences between scalar and vector quantities. The chapter covers topics such as equality, addition, and multiplication of vectors, angular frequency and velocity, displacement and more.
This chapter further explains the motion of an object and the effect external forces can have on it. We will learn about the direction and magnitude of the force and the effects of gravitation. There are numerical problems and graphical representation to calculate the time and speed of moving objects.
In this chapter, we learn the theoretical concept of rotational motion and also the mathematical method of its calculation. The NCERT solutions will make the concepts clear and deepen the students understanding of the chapter.
Here students will learn about certain common physical properties of solids such as density, elasticity, tensile strength, volume strain, etc. We will see the real-life applications of certain solids such as steel and copper.
In this chapter, we will learn the concept and definitions of heat and temperature. We will learn how different matter behaves differently when the heat is applied to it. There are some mathematical problems about the conversion of celsius and kelvin.
Students will study in detail about oscillations and oscillatory motion. They will need to learn about periodic motion and harmonic motion and problems regarding them as well as their graphical representation.

This will help students clear their concepts, solve their doubts, practice numerical problems all from the comfort of their home. With the right tools at their disposal, students are ensured of a good result.
Answer: A metal expands on heating. If a hole is made in the metal plate, the hole will also expand due to the expansion of the material. It can be explained by considering the air in the region of the hole and that air will also expand on heating. Therefore, the diameter of the hole increases always.
Answer: A body absorbs and emits thermal radiations at all temperatures except absolute zero, hence option A is incorrect.
Thermal radiations like all forms of radiation are electromagnetic in nature. Hence option B is correct.
All electromagnetic radiations reflect off mirrors, hence option C is incorrect.
All the electromagnetic radiation like thermal radiations travel with the velocity of the speed of light. Hence option D is correct.

Physics involves problem-solving and critical thinking. NCERT solutions include a variety of exercises that require students to apply concepts to solve problems. Practicing these problems hones their analytical and problem-solving skills. It often involves visual concepts, such as diagrams, graphs, and illustrations. NCERT solutions use these visual aids to explain concepts, making it easier for students to grasp abstract ideas.
Mechanics and properties of matter, Heat and thermodynamics, Sound or acoustics, Electricity and magnetism, Modern physics, Biophysics, Astrophysics, Geophysics, Nuclear physics, etc. Physics is based on mathematical equations and formulas. NCERT solutions break down these equations step by step, making it easier for students to understand how they are derived and applied.
1. Classical Mechanics: It explains the motion of particles which travel with velocities much less than that of light.
2. Theory of Relativity: It explains the in-variance in nature and also the motion of particles which travel with velocities close to that of light.
3. Thermodynamics: It is the theory of heat, temperature and conversion of heat into work and vice-versa. It also explains the behaviours of systems containing very large number of particles.
NCERT solutions often include real-life examples that demonstrate the practical applications of physics concepts. This helps students relate theoretical concepts to the world around them.
