The fundamental physics of space missions relies on orbital mechanics, balancing gravitational pull with the centrifugal force of the satellite. Types of Orbit Low Earth Orbit (LEO): Altitude...
Indian Astronomical Observatory (IAO), Hanle Location and Geography: Situated at Mount Saraswati in the Hanle Valley of southeastern Ladakh at an altitude of 4,500 meters (14,764 feet). It...
LIGO-India Gravitational Wave Observatory Context: Construction is underway for India’s first Laser Interferometer Gravitational-Wave Observatory (LIGO) in Hingoli, Maharashtra. Core Physics Principle: Employs the principle of Michelson Interferometry...
Absolute Space and Time Standards The fundamental difference between inertial and non-inertial frames of reference is the presence of pseudo-forces; inertial frames obey Newton’s laws of motion without...
The International System of Units (Système International d'Unités or SI) is the modern metric system of measurement used universally in science, technology, and commerce. Maintained by the International...
Mechanics covers the motion of bodies, forces, and energy conversions. Equations of Motion (Uniform Acceleration) These equations govern the linear motion of objects experiencing constant acceleration. First Equation...
Scientific instruments form a crucial part of the Applied Physics syllabus for the UPSC Civil Services Examination (Prelims). Questions frequently test the functional application, underlying principles, and everyday...
Classical Mechanics, Gravity, and Astronomy Galileo Galilei Galileo Galilei is considered the pioneer of modern observational astronomy and experimental physics. Key Discoveries: Formulated the Law of Inertia (which...
Newton’s Laws of Motion and Galilean Relativity Newton’s three laws of motion form the bedrock of classical mechanics, governing how forces interact with mass. First Law (Law of...
Remote sensing is the science of acquiring information about an object or phenomenon without making physical contact, primarily utilizing electromagnetic radiation (EMR). In disaster management, it serves as...
