This document contains flashcards for various Physics topics relevant to the JEE MAIN exam, covering concepts from Vectors to Semiconductor Physics.

Vector

A quantity with both magnitude and direction.

Unit & Dimensions

Units represent physical quantities, while dimensions describe their fundamental nature.

Kinematics

The study of motion without considering its causes.

NLM

Newton's Laws of Motion, describing the relationship between a body and the forces acting upon it.

Circular Motion

Movement of an object along the circumference of a circle or rotation along a circular path.

Work Power Energy

Work is the energy transfer, power is the rate of doing work, and energy is the ability to do work.

Centre of Mass

The unique point where the weighted relative position of the distributed mass sums to zero.

Rotational Motion

Motion of a rigid body in which all particles in the body move in circles about an axis.

Gravitation

The force of attraction between all masses in the universe.

Elasticity

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.

Fluid

A substance that has no fixed shape and yields easily to external pressure; a gas or liquid.

KTG Thermodynamics

Kinetic Theory of Gases explains macroscopic properties of gases in terms of the motion of constituent particles; Thermodynamics deals with heat and temperature and their relation to energy and work.

SHM

Simple Harmonic Motion, a type of periodic motion where the restoring force is proportional to the displacement.

Wave Motion & Sound Wave

Wave motion is the transfer of energy through a medium, and sound waves are mechanical waves that propagate through a medium.

Electrostatics

Deals with the phenomena and properties of stationary or slow-moving electric charges

Capacitor

An electrical component used to store electrical energy in an electric field.

Current Electricity

The flow of electric charge through a conductor.

Magnetic Effect of Current

The magnetic field created by moving electric charges.

EMI & AC

Electromagnetic Induction and Alternating Current, dealing with electromagnetic induction and alternating currents and circuits.

EMW

Electromagnetic Waves, a form of energy that propagates through space as oscillating electric and magnetic fields.

Geometrical Optics

Deals with light as rays and studies image formation through lenses and mirrors.

Wave Optics

Studies phenomena where light exhibits wave-like properties, such as interference and diffraction.

Modern Physics

Encompasses theories developed in the early 20th century and beyond, including relativity and quantum mechanics.

Semiconductor

A material with electrical conductivity between a conductor and an insulator.

Error & Practical Physics

Error analysis in experimental measurements and practical applications of Physics principles.
