  • Chapter 6. Tissue
    Tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
  • Chapter 7.The living World
    The living world comprises an amazing diversity of living organisms. ... The description of living organisms including human beings began much later in human history. Societies which indulged in anthropocentric view of biology could register limited progress in biological knowledge.
  • Chapter 8. Biological Classification
    Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.
  • Chapter 9. Plant Kingdom
    R.H. Whittaker organized the organisms into five kingdoms. He classified organisms on the basis of cell structure, mode, and source of nutrition and body design. The five kingdoms proposed by Whittaker are Monera, Protista, Fungi, Plantae, and Animalia. Let's learn about the plant kingdom i.e., kingdom Plantae.
  • Chapter 10. Morphology of Flowering Plant
    Even though the angiosperms show such a large diversity in external structure or morphology, they are all characterised by presence of roots, stems, leaves, flowers and fruits. ... The underground part of the flowering plant is the root system while the portion above the ground forms the shoot system

  • Chapter 6. Thermodynamics & themochemistry (Class XI)
    Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Thermochemistry is the study of the heat energy associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling.
  • Chapter 3. Classification of Hements AND Peridocity (Class XI)
    Classification of elements into groups and development of Periodic Law and Periodic Table are the consequences of systematising the knowledge gained by a number of scientists through their observations and experiments. The German chemist, Johann Dobereiner in early 1800’s was the first to consider the idea of trends among properties of elements.

Trigonometry review Vectors : Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude
  • Chapter 2. Differentiation (Class XI)
    The flow is the time derivative of the water in the bucket. The basic ideas are not more difficult than that. Calculus analyses things that change, and physics is much concerned with changes. For physics, you'll need at least some of the simplest and most important concepts from calculus.
  • Chapter 3. Circular Motion (Class XI)
    In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. ... Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation.
  • Chapter 4. Kinematics (Class XI)
    Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).
  • Chapter 5. Lwas of Motion & Friction (Class XI)
    Newton worked in many areas of mathematics and physics. ... Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. a force must act in the direction opposite to that of the motion. Friction is a force that opposes the motion of an object. There are different types of friction, such as static, fluid and rolling friction. We measure friction in terms of kinetic friction and static friction.
  • Chapter 6. Work power & energy (Class XI)
    In physics, work is related to the amount of energy transferred to or from a system by a force. It is a scalar-valued quantity with SI units of Joule.
  • Chapter 7. System of particles & Rotational Motion
    A system of particles means a group of particles inter-related. The equations for a system of particles can be readily used to develop those for a rigid body. One new but very important concept introduced with a system of particles is the center of mass. The following quantities are covered in this section uniform circular motion describes the motion of a body traversing a circular path at constant speed. ... This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
  • Chapter 8. Machenica property of solid (Class XI)
    Mechanical Properties of solids describe characteristics such as their strength and resistance to deformation. It describes about the ability of an object to withstand the stress applied to that object. Objects also resist changing their shape.
  • Chapter 9. Gravitation (Class XI)
    Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
  • Chapter 10. Fluids (Class XI)
    a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas, and to some extent, plastic solids. ... The distinction is made by evaluating the viscosity of the substance.
  • Chapter 11. Thermal Properties of Matter (Class XI)
    Heat is the form of energy transferred between two (or more) systems or a system and its surroundings by virtue of temperature difference. ... Temperature of a substance is a physical quantity which measures the degree of hotness or coldness of the substance.
  • Chapter 12. Simple Harmonic Motion Oscillation (Class XI)
    In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. ... The motion is sinusoidal in time and demonstrates a single resonant frequency.
  • Chapter 13. 2-D Collision (Class XI)
    If two objects make a head on collision, they can bounce and move along the same direction they approached from (i.e. only a single dimension). However, if two objects make a glancing collision, they'll move off in two dimensions after the collision (like a glancing collision between two billiard balls).
  • Chapter 14. Waves (Class XI)
    Further, the behavior of particles in quantum mechanics are described by waves. ... A wave can be transverse, where a disturbance creates oscillations that are perpendicular to the propagation of energy transfer, or longitudinal: the oscillations are parallel to the direction of energy propagation.
  • Chapter 15. Mathematics tools (Class XI)
    Mathematics epitomizes the word "abstract." But still this can't be the complete story because many mathematical structures can be used to describe how physical objects interact and the nature of the relationships among them. In physics we use mathematics as a tool to understand Nature.
  • Chapter 16. Thermodynamics & KTG
    Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy. In particular, it describes how thermal energy is converted to and from other forms of energy and how it affects matter.
