Physics NCERT Solutions
If you’re falling behind in your Physics class, you’ve come to the right place –get all you need to know about the Class 11 Physics NCERT Solutions here. Below we detail the contents of each chapter and include the NCERT Solutions for each chapter of Class 11 Physics.
Understanding the concepts and theories as stated by famous physicians, regarding the world around us. This is an introduction to the world of Physics.
Practising problems of volume and surface area, and learning to convert to congruent units during different measurements and problems. Some problems in this set are simply mathematical problems, and others are word problems, which have to be expressed in mathematical terms first before they can be solved.
Chapter 3: Motion in a Straight Line
This chapter covers the ins and outs of rectilinear motion or motion in a straight line, regardless of whether it is in one plane or across multiple planes. Some of the practice questions in this chapter are also simple mathematical problems with an accompanying graph to demonstrate the trajectory of motion. In others, the problems are described in words and must be quantified in mathematical terms first before they can be solved. Many of these questions are multi-part, where the answers from the first will influence the answers of the other parts.
This chapter focuses on determining whether physical quantities are scalar or vector with factors including volume, mass, speed, acceleration, density, number of moles, velocity, angular frequency, displacement, and angular velocity.
Chapter 5: Laws of motion
In this chapter, the topics covered include magnitude and direction of force, calculating time, speed, and velocity. Some problems in this segment also use position-time graphs of various objects in motion, to figure out various factors such as time and speed of the moving object.
Chapter 6: Work Energy and Power
Problems in this chapter focus on calculating the work done in the application of a force, and the amount energy utilized by objects.
Chapter 7: System of Particles and Rotational Motion
This chapter focuses on the calculation of rotational motion, as well as charting the movement of molecules as they move from one point to another. Problems in this chapter require solving for distance, displacement, increase in kinetic energy, and the like.
Chapter 8: Gravitation
This chapter focuses entirely on gravitation. There are a few questions on the theoretical notion behind gravitation force, which compel students to apply their theoretical knowledge to abstract questions. In addition, there are mathematical problems which account for gravitational force in the calculation of time, speed, and distance of objects in motion.
The problems in this chapter are geared towards some real applications of physics. Hence, this chapter focuses on the mechanical properties of solids, such as steel and copper. Many of these questions account for dimensions of solid materials, the force applied to each object, and calculate for Young’s modulus, the yield strength of each material, etc.
Chapter 10: Mechanical Properties of Fluids
In continuation of the previous chapter, this chapter focuses on the mechanical properties of fluids. Accounting for factors such as atmospheric pressure, blood pressure, the surface tension of liquids, the problems ask to explain why fluids behave differently under different environmental conditions in the first segment of the problem set. In the second segment, problems require calculations for pressure exerted by objects, application of Bernoulli’s equation, and the like.
As the precursor, the next chapter, this chapter introduces the concept of temperature. With basic calculations for temperature conversions between Celsius and Kelvin at first, the problems span to various levels of difficulty including questions about materials of varying dimensions under different conditions, and their tendency to behave differently in differing temperatures.
In continuation of the last chapter, this chapter focuses on thermodynamics. This chapter covers topics such as the effects of heat from combustion, the extent of heat needed to raise the temperature of different elements, the net work done by a system under varying temperatures and conditions.
This chapter elaborates on STP, measuring differences in molecular volume, problems also surround changes in pressure, volume, and temperature, and some problems include graphical components to illustrate and solve these problems.
Chapter 14: Oscillations
This chapter covers oscillations and problems which require discerning periodic motion and harmonic motion, in some problems graphical expressions of linear motions of a particle are used to calculate the period of motion. Problems are of varying levels of difficulty and follow a natural progression.
Chapter 15: Waves
In the last chapter, the problems focus on the movement of waves, calculating for the amount of time taken by waves to cover a distance, given specifications, using functions to express the motion of a traveling wave, calculating for the time taken for sound to reach in air and in water, and various word problems which require mathematical and graphical expressions before calculations.
