Physics is an important science subject and we prepared Physics notes very carefully. We are providing Math 1st year notes of the Punjab board.
Class xi Physics Notes Chapter 1
Measurements the first chapter of 1st-year Physics notes PDF format. You will read in this chapter about Physics, Physics deals with the study of matter, energy, and their relationship.
Investigating the rules of motion, the geometry of space and time, the types of forces that hold various materials together, the interactions of various particles, and the interactions of electromagnetic radiation with matter and energy are all part of the study of physics.
The fundamental building blocks of physics are the physical quantities that are used to express the rules of physics. Therefore, reliable measurements of these quantities are required. There are several of these, including mass, time, length, velocity, density, force, temperature, and electric current.
You will read about radian, steradian, and international unit systems, errors and uncertainties, significant figures, precision, and accuracy. It is required to consider the likely uncertainties in all the elements contributing to that calculation in order to determine the total uncertainty or mistake.
Physics Notes 11 class Chapter 2
Vectors And Equilibrium second chapter of Physics 1st year notes Punjab board. You can define physical quantities that have both numerical and directional properties called vectors.
This chapter discusses vector algebra and how it can be used to solve issues involving torque and force equilibrium. You will be able to describe basic concepts of vectors, vector addition by rectangular components, the product of two vectors, torque, and equilibrium of forces.
Space directions are described by unit vectors. A vector with no units has a magnitude of 1. The torque is defined as the product of the moment arm and the force. The arm of the moment is the length measured perpendicularly from the rotational axis to the force’s direction of action.
Class 11 Notes Physics Chapter 3
Motion And Force is the third chapter of Physics 1st year notes PDF. Our universe is constantly in motion. The atoms are constantly moving in every component of stuff.
We move about the surface of the Earth, while the Earth moves in its orbit around the Sun. The Sun and the stars are in motion, Everything in the vastness of space is in a state of perpetual motion.
You will be able to define displacement, velocity, acceleration, and velocity-time graph, and review equations of uniformly accelerated motion, momentum, inelastic and elastic collisions, water flow forces, momentum, Newton’s law of motion, explosive forces, and projectile motion.
Newton’s First Law of Motion, a body at rest will remain at rest, and a body moving with uniform velocity will continue to do so unless acted upon by some unbalanced external force.
Newton’s Second Law of Motion, when a force is applied to a body, it accelerates in that direction. The acceleration that is created changes inversely with body mass and directly with the applied force.
Newton‘s Third Law of Motion, action, and reaction are equal and opposite. For example, whenever an interaction occurs between two objects, each object exerts the same force on the other, but in the opposite direction and for the same length of time.
Each of the forces in the action-reaction combination only affects the action, one of the two bodies. forces never affect the same body twice.
Notes Physics 11 Class Chapter 4
Work And Energy is the fourth chapter of Physics 1st year notes Punjab board. Work is often thought of in terms of physical or mental effort. However, the terms “work” and “displacement” are used interchangeably in physics. We’ll start with a straightforward scenario in which work is being done by a continuous force.
You will read in this chapter about work done by a variable force, a constant force, and work done by the gravitational field. Work done in the Earth’s gravitational field is independent of the path followed.
Define energy, power, interconversion of potential and kinetic energy, and energy conservation. Energy is unbreakable. Although it can change from one kind to another, the overall amount of energy does not change.
You can describe alternative energy sources, These are the energy sources that are not very common these days. However, it is expected that these sources will contribute substantially to the energy demand of the future.
1st Year Physics Notes Chapter 5
Circular Motion is the fifth chapter of the 11-class Physics notes solution guide. In this chapter, we will study, rotational motion, angular momentum, circular motion, and the moment of inertia.
You will read about centripetal force, angular displacement, angular acceleration, angular velocity, the moment of inertia, and the relation between angular and linear velocities.
The law of conservation of angular momentum, weightlessness in satellites, real and apparent weight, gravity-free system, orbital velocity, geostationary orbits, artificial gravity, Newton’s and Einstein’s views of gravitation, communication satellites, and rotational kinetic energy.
Physics 1st Year Notes Chapter 6
Fluid Dynamics is the sixth chapter of Physics class 11 notes. Although the research of fluids in motion is rather complex, analysis can be made simpler by assuming a few things. The application of two significant conservation concepts greatly simplifies the analysis:
- mass-energy conservation
- an effort to conserve energy.
The Bernoulli equation is founded on the law of energy conservation, while the principle of mass conservation provides us with the equation of continuity.
The relationship between Bernoulli’s equation and the equation for continuity applications in aeroplane and blood circulation are discussed in this chapter.
You will be able to define Stokes’ law and viscous drag velocity of the terminal and fluid flow, the flow is said to be streamlined or laminar if each particle that crosses a specific spot, moves along exactly the same path, as followed by passing particles that point earlier.
Describe the continuity equation, the equation of Bernoulli’s, and Bernoulli’s equation applications.
Notes 1st Year Physics Chapter 7
Oscillations seventh chapter of Physics 1st year notes. Many times, we come across a type of motion in which a body rotates around a neutral position. It is referred to as vibratory motion or oscillatory motion.
When an oscillatory motion repeats itself at regular intervals, it is referred to as periodic. Describe phase, a horizontal mass-spring system, simple harmonic motion (SHM) and a basic pendulum are examples of SHM.
You can define free and forced oscillations, when a body oscillates without the influence of an outside force, it is said to be performing free vibrations. The frequency of these free vibrations is known as its natural frequency.
Physics Notes 1st Year Chapter 8
Waves eighth chapter of Physics 1st year notes. You will read in this chapter about wave types and kinds of waves, for example, water waves, and sound waves.
Waves don’t transport matter, they move energy.
A disturbance that propagates out from a source carries energy. We are knowledgeable about many forms of waves, such as ocean water waves.
There is always a series of oscillatory motions. The oscillation in the vibrating body causes the wave to be created, and oscillations are how the wave travels over space. The oscillating waves that are propagated by material particles are known as mechanical waves.
You will define beats, interference, the principle of superposition, the speed of sound in air, progressive waves, and periodic waves. In the water, throw a stone. There will be ripples that travel across the water. Examples of progressive waves are ripples.
The Doppler effect is a significant wave phenomenon. This result demonstrates that if there is any relative motion between the wave source and the observer notices what appears to be a shift in the waves’ frequency.
You can explain stationary waves in air columns, stationary waves in a stretched string, stationary waves, and reflection of waves.
Physics 11 Class Notes Chapter 9
Physical Optics‘ ninth chapter of Physics 1st year notes. You can be able to define Michelson’s interferometer, Newton’s rings, interference in films, Young’s double-slit experiment, interference of light waves, Huygens principle, and wavefronts.
Such a surface on which all the points have the same phase of vibration is known as a wavefront. A transparent substance with a thickness that is similar to the wavelength of light is called a thin film.
Due to the interference of light reflected from the two, soap bubbles and the oil coating on the water’s surface have brilliant and lovely colors.
An instrument that can be utilized is Michelson’s interferometer to estimate distance with the highest degree of accuracy. In 1881, Michelson created this device based on the notion of light-ray interference.
You will read about polarization, diffraction of X-Rays by crystals, diffraction grating, diffraction due to a narrow slit, and diffraction of light.
Diffraction is the process through which light bends around objects and disperses into the geometric shadow of an object.
Class 11 Physics Notes Chapter 10
Optical Instruments tenth chapter of Physics 1st year notes. Some optical instruments that are based on the principles of reflection and refraction, will be discussed. The most common of these instruments are the compound microscope, magnifying glass, and telescopes.
You will also study the magnification and resolving powers of these optical instruments. You will read about spectrometers, astronomical telescopes, compound microscopes, simple microscopes, magnifying power and resolving power of optical instruments, and the least distance of distinct vision.
The shortest visual distance, also known as the near point, is the shortest distance from the eye at which an item seems to be distinct. The ratio of the size of the image to the size
of the object is called magnification.
The resolving power of an instrument is its ability to reveal
the minor details of the object under examination. A spectrometer is an optical tool used to examine the spectra of various light sources. With the help of a spectrometer.
You will be able to define the losses of power, the speed of light, signal transmission and conversion to sound, types of optical fibers, fiber optic principles, and the introduction of fiber optics.
Notes Class 11 Physics Chapter 11
Heat And Thermodynamics eleventh chapter of Physics 1st year notes Punjab board. You will study irreversible and reversible processes, molar-specific heats of a gas, the first law of thermodynamics, work, and heat, internal energy, and kinetic theory of gases.
Some thermal energy is converted to mechanical work by a heat engine. Typically, the heat is produced when fuel is burned. The steam engine was the first type of heat source.
It was based on the observation that when water is heated in a container with a lid on top, the steam inside seeks to push the lid off, demonstrating the steam’s ability to exert force. This discovery influenced the creation of the steam engine.
You will learn about the environmental crisis as entropy crisis, entropy, the petrol engine, the thermodynamic scale of temperature, the Carnot engine and Carnot’s theorem, the second law of thermodynamics, and the heat engine.
