This chapter introduces us to physics and its branches. Physics is related to mathematics, chemistry, astronomy, biology, and meteorology. There are four fundamental forces in nature that we study under physics that are gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. The solutions for this chapter by Equal Shiksha will aid you to have a better understanding of the concepts.
This chapter tells us about the international system of units, measurement of length, measurement of mass, and measurement of time. We further understand about the accuracy, precision of instruments, and errors in measurement, these errors could be systematic errors, random errors, and least count errors. Check out the solutions for this chapter by Ekal Shiksha.
Everything in the universe moves, and there are two branches in physics that examine the motion of an object, which are kinematics and dynamics. Kinematics describes the motion without looking at the cause of it, whereas dynamics leads the motion of objects to the forces which caused them. Motions of objects can be of three types, one dimensional, two dimensional and three dimensional. Check out the solutions for this chapter by Ekal Shiksha.
In this chapter, we study motion in a plane which is also called two dimensional motion. To understand motion in a plane, we must also understand vectors, as we use vectors for defining velocity and acceleration in a plane. This chapter tells us about the multiplication, addition, and subtraction of vectors. The solutions for this chapter by Eagle Shiksha have detailed answers to NCERT questions.
Now that we know that all things in the universe move, now this chapter tells us about the laws that these moving bodies follow. The most important laws of motion are Newton’s law of motion. There are three laws of motion that Newton gave, in this chapter, we understand each of the laws throughly. The solutions for this chapter by Ekal Shiksha will aid you to have a thorough understanding of the concepts.
In this chapter, we understand how to calculate work, energy, and power. Work done is a scalar quantity measured in newtonmetre or joules. Energy is also measured in the same unit as work ie, joules. Energy can be of two types, kinetic energy, and potential energy. Power is the rate at which work is done or energy is transferred and is measured in Watts. The solutions for this chapter by Eka Shiksha have detailed answers to NCERT questions given in the back exercise.
Some of the topics covered under this chapter are center of mass, motion of center of mass, linear momentum of a system of particles, vector product of two vectors, angular velocity and acceleration with linear velocity, torque and angular momentum, equilibrium of rigid body, moment of inertia, theorems of perpendicular and parallel axis and some others. The solutions for this chapter by Ekal Shiksha will aid you to have a thorough understanding of the concepts.
In this chapter, firstly we read about Kepler’s law of orbits, areas, and periods. By understanding these laws, we are better able to understand the universal law of gravitation. Newton gave the universal law of gravitation. In the chapter, we mathematically understand the law of gravitation. Further, we learn about the gravitational constant acceleration due to the gravity of the earth, and gravitational potential energy. The solutions for this chapter by Ekal Shiksha will aid you to have a thorough understanding of the concepts.
This chapter tells us about the elastic behavior of solids. Topics such as stress and strain are introduced in the chapter. We read about the Hooke’s law and understand how to make a stress-strain curve. Further, we understand the applications of elastic behavior of materials. The solutions for this chapter by Ekal Shiksha have detailed answers to NCERT questions along with diagrammatical representations.
This chapter talks about the mechanical properties of fluids, which are substances which can flow. Pressure is the thrust experienced per unit area of the surface, the measuring unit of pressure is a Pascal. Through this chapter, we also learn about streamline flow, streamline is the path taken by a fluid particle under a steady flow. Another topic of this chapter is viscosity, which is the resistance to fluid motion. Check out the solutions for this chapter by Ekal Shiksha.
This chapter is about the thermal properties of matter. In this chapter, we learn about temperature and heat measurement of temperature, ideal gas situation, absolute temperature, thermal expansion, specific heat capacity, calorimeter, change of state, heat transfer, and Newton’s law of cooling. Check out the solutions for this chapter curated by experts at Ekal Shiksha.
This chapter tells us about the laws that govern thermal energy. We understand the Zeroth law of thermodynamics , first law of thermodynamics, thermodynamic state variables and equation of state thermodynamic processes, heat engines, refrigerators and heat pumps, Second law of thermodynamics and reversible and irreversible processes. The solutions for this chapter by Ekal Shiksha will aid you to have a thorough understanding of the concepts.
This chapter talks about the kinetic theory that was developed by Maxwell, Boltzmann, and others. It is a theory that explains the behavior of gases, assuming that gas consists of rapidly moving atoms of molecules. In this chapter we learn about the Boyle’a Law, Charle’s law, and Gay Lussac’s law about the gas. We also understand the law of equipartition of energy in gas. Check out the solutions for this chapter by Ekal Shiksha.
The topics that we study under this chapter are periodic and oscillatory motions, simple harmonic motions, uniform circular motions, and velocity and acceleration in each of these motions. Further, we understand the force law of simple harmonic motion and the energy in simple harmonic motion. Check out the NCERT solutions for this chapter by Ekal Shiksha.
