  • Chapter 18 Center of Mass (Class XI)
    The terms center of mass and center of gravity are used synonymously in a uniform gravity field to represent the unique point in an object or system which can be used to describe the system's response to external forces and torques. The concept of the center of mass is that of an average of the masses factored by their distances from a reference point. In one plane, that is like the balancing of a seesaw about a pivot point with respect to the torques produced.
  • Chapter 17 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 15 Collision (Class XI)
    Collisions involve forces (there is a change in velocity). ... Specifically, collisions can either be elastic, meaning they conserve both momentum and kinetic energy, or inelastic, meaning they conserve momentum but not kinetic energy. An inelastic collision is sometimes also called a plastic collision.
  • Chapter 10 Fluid Dynamics (Class XI)
    In physics, 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 16 Friction (Class XI)
    This force is static friction force, which is the force exerted on the surface by another when there is no motion between the two surfaces. Static friction force acts in response to a force trying to cause a stationary object to start moving.
  • Chapter 11 Gravitation (Class XI)
    Kepler's laws of planetary motion.The universal law of gravitation. Acceleration due to gravity and its variation with altitude and depth. Gravitational potential energy and gravitational potential. Escape velocity. Orbital velocity of a satellite. Geo-stationary satellites,
  • Chapter 5 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 6 Newton's law of Motion (Class XI)
    Intuitive concept of force. Inertia, Newton's first law of motion; momentum and Newton's second law of motion; impulse; Newton's third law of motion. Law of conservation of linear momentum and its applications. Equilibrium of concurrent forces. Static and kinetic friction, laws of friction, rolling friction, lubrication. Dynamics of uniform circular motion: Centripetal force, examples of circular motion (vehicle on a level circular road, vehicle on banked road).
  • Chapter 9 Rotation rigid body dynamics (Class XI)
    Center of mass of a two-particle system, momentum conservation and center of mass motion. Center of mass of a rigid body; center of mass of a uniform rod. Moment of a force, torque, angular momentum, laws of conservation of angular momentum and its applications. Equilibrium of rigid bodies, rigid body rotation and equations of rotational motion, comparison of linear and rotational motions. Moment of inertia, radius of gyration.Values of moments of inertia, for simple geometrical objects (no derivation). Statement of parallel and perpendicular axes theorems and their applications.
  • Chapter 14 Waves (Class XI)
    Transverse and longitudinal waves, speed of wave motion. Displacement relation for a progressive wave. Principle of superposition of waves, reflection of waves, standing waves in strings and organ pipes, fundamental mode and harmonics, Beats, Doppler effect.
  • Chapter 7 Work power & energy (Class XI)
    Work done by a constant force and a variable force, kinetic energy, work-energy theorem, power, Notion of potential energy, potential energy of a spring, conservative forces conservation of mechanical energy (kinetic and potential energies) non-conservative forces: motion in a vertical circle; elastic and inelastic collisions in one and two dimensions.
  • 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 1 Basic Maths (Class XI)
    Mathematics is vital to your study of physics, Algebra is needed to isolate and solve for whatever variable is desired, Physics often deals with very large or very small values,
  • Chapter 3 Integration (Class XI)
    integration is easier than you think. Here's a simple example, the bucket at right integrates the flow from the tap over time. The flow is the time derivative of the water in the bucket Calculus analyses things that change, and physics is much concerned with changes,
  • Chapter 4 Vector (Class XI)
    Vector. 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. Although a vector has magnitude and direction, it does not have position.
  • Chapter 8 System of Particles (Class XI)
    Under certain circumstances the linear momentum of a system is conserved. The linear momentum of a particle is related to the net force acting on that object: ... " The linear momentum of a system of particles is equal to the product of the total mass M of the system and the velocity of the center of mass.
  • Chapter 12 Heat & Thermodynamics (Class XI)
    Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy Thermal energy is the energy a substance or system has due to its temperature,the energy of moving or vibrating molecules, according to the Energy Education website of the Texas Education Agency
  • Chapter 13 SHM & Elasticity (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. In physics, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
