JEE Main 2020 Physics Top 100 Questions

The systematic study of matter and its motion through space and time, along with related concepts such as energy and force.

The standardized system used to measure physical quantities like length, mass, and time. This system makes it easier to communicate measurements and perform calculations in science.

A quantity representing a direction and magnitude, often used to represent forces, velocities, and displacements.

The study of motion without focusing on the forces that cause it. It involves concepts like displacement, velocity, and acceleration.

The fundamental laws that govern how objects move and interact due to forces. These laws include Newton's Laws of Motion.

Concepts related to work, energy, and power. Work is done by applying force to move something, and energy is the capacity to do work.

The point where the entire mass of an object can be considered concentrated. It's useful for analyzing the motion of extended objects.

The study of how objects rotate and how forces affect their rotation. Concepts include torque, angular momentum, and moment of inertia.

The study of how forces affect the motion of objects. It explains why objects accelerate, decelerate, or stay still.

The center of mass of a system is the point that represents the average location of all the mass in that system. It's like a 'balancing point'.

Study of how objects move when they collide. It deals with conservation of momentum, impulse, and energy involved in a collision.

Study of how objects rotate around an axis. It involves concepts like angular velocity, torque, and moment of inertia.

The study of how objects move due to the force of gravity. It explains the motion of planets around the sun, falling objects, and tides.

Study of electricity at rest, dealing with electric charges, fields, and potential. It's about how electric charges interact.

The study of fluids in motion, such as liquids and gases, exploring concepts like pressure, buoyancy, viscosity, and fluid flow.

A type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium.

A branch of physics that studies the relationship between heat, work, and energy, focusing on concepts like entropy, enthalpy, and the laws of thermodynamics.

Passive electrical components that store electrical energy in an electric field, working on the principle of capacitance.

The study of the flow of electric charge through materials, covering concepts like resistance, current, voltage, and power.

Deals with the effects of magnetic fields on moving electric charges, including topics like magnetic forces, magnetic fields, and electromagnetic induction.

The study of the generation of electric current by changing magnetic fields, exploring concepts like Faraday's law, Lenz's law, and induced electromotive force (EMF).

The study of light and its properties, including wave-like behavior, interference, and diffraction.

Materials that have conductivity between conductors and insulators. Their conductivity can be controlled by adding impurities or applying an electric field.

A type of radiation that includes visible light, infrared, ultraviolet, and other forms of electromagnetic waves, all travelling at the speed of light.

A branch of physics that explores the behavior of matter and energy at the atomic and subatomic level, including phenomena like the photoelectric effect and the quantization of energy.

The photoelectric effect is the emission of electrons from a metal surface when light falls on it.

The principle that energy exists in discrete packets called quanta. It explains the emission and absorption of light by atoms.

A phenomenon where the wave nature of light causes it to bend around corners or obstacles.

The interference of waves, especially light waves, resulting in patterns of constructive and destructive interference.
