Physical World

Key notes for class XI Physics chapter 01 Physical World it includes revision notes such as There are four fundamental forces which govern both macroscopic and microscopic phenomena.

Units And Measurements

Key notes for class XI Physics chapter 01 Units And Measurements it includes revision notes such as Physics is a quantitative science, based on measurement of physical quantities. Certain physical quantities have been chosen as fundamental or base quantities (such as length,mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity).

Motion In A Straight Line

Key notes for class XI Physics chapter 03 Motion In A Straight Line it includes revision notes such as An object is said to be in motion if its position changes with time. The position of the object can be specified with reference to a conveniently chosen origin. For motion in a straight line, position to the right of the origin is taken as positive and to the left as negative.

Motion In A Plane

Key notes for class XI Physics chapter 04 Motion In A Plane it inlcudes revision notes such as Scalar quantities have only magnitude. Examples are distance, speed, mass and temperature.

Law Of Motion

Key notes for class XI Physics chapter 05 Law Of Motion it includes revision notes such as Aristotleís view that a force is necessary to keep a body in uniform motion is wrong. A force is necessary in practice to counter the opposing force of friction.

Work, Energy and Power

Key notes for class XI Physics chapter 06 Work, Energy and Power it includes revision notes such as The work-energy theorem states that the change in kinetic energy of a body is the workdone by the net force on the body.

System of Particles and Rotational Motion

Key notes for class XI Physics chapter 07 System of Particles and Rotational Motion it inlcudes revision notes such as Ideally, a rigid body is one for which the distances between different particles of the body do not change, even though there are forces on them.

Gravitation

Key notes for class XI Physics chapter 08 Gravitation it includes revision notes such as  Kepler's first law (law of orbit): Every planet revolves around the sun in an elliptical orbit with the sun is situated at one focus of the ellipse.

Mechanical Properties of Solids

Key notes for class XI Physics chapter 09 Mechanical Properties of Solids it includes revision notes such as A force which produces a change in configuration of the object on applying it, is called a deforming force.

Mechanical Properties of Fluids

Key notes for class XI Physics chapter 10 Mechanical Properties of Fluids it includes revision notes such as  Fluids are those substances which can flow when an external force is applied on it. Liquids and gases are fluids.

Thermal Properties of Matter

Key notes for class XI Physics chapter 11 Thermal Properties of Matter it includes revision notes such as The branch dealing with measurement of temperature is called thremometry and the devices used to measure temperature are called thermometers.

Thermodynamics

Key notes for class XI Physics chapter 12 Thermodynamics it includes revision notes such as An assemnbly of externely large number of gas molecules is called a themodynamical system. The pressure P, volume V, temperate T and heat cotent Q are called Therodynamical parameters.

Kinetic Theory

Key notes for class XI Physics chapter 13 Kinetic Theory it includes revision notes such as At constant pressure volume of a given mass of gas is directly proportional to its absolute temperature.

Oscillations

Key notes for class XI Physics chapter 14 Oscillations it includes revision notes such as Periodic and oscillatory motions Simple harmonic motion and its equations Free, forced and damped oscillations, Resonance

Waves

Key notes for class XI Physics chapter 15 Waves it includes revision notes such as Transverse and longitudinal waves, Displacement relation in a progressive wave, The speed of a travelling wave, The principle of superposition of waves, Reflection of waves, Beats, Doppler effect When sound travels in gas then changes take in the medium are isothermal in nature. Phase is the argument of the sine or cosine function representing the wave.
