Elastic Collisions: Perfect Conservation of Energy and Momentum
In an elastic collision, both kinetic energy and linear momentum are conserved. This means that: Elastic collisions are idealized and
Impulse: Force Applied Over Time Changes Momentum
Impulse is a measure of how much a force changes an object’s momentum when applied over a certain period of
Conservation of Linear Momentum: Motion Preserved in Isolation
The conservation of linear momentum is a fundamental principle in physics stating that the total linear momentum of an isolated
Centripetal Force: The Inward Pull Behind Circular Motion
Centripetal force is the net force that keeps an object moving in a circular path. It always acts toward the
Hardy’s Paradox: A Quantum Contradiction Without Entanglement
Hardy’s paradox, proposed by physicist Lucien Hardy in 1992, reveals a deep and surprising conflict between quantum mechanics and classical
Quantum Steering: Remote Influence in Entangled Systems
Quantum steering is a striking form of quantum nonlocality, where the measurement choices made on one part of an entangled
Kochen–Specker Theorem: The Context Matters in Quantum Reality
The Kochen–Specker theorem, developed in 1967 by Simon Kochen and Ernst Specker, is a fundamental result in quantum foundations. It
Leggett–Garg Inequalities: Probing Quantum Behavior in the Macroscopic World
The Leggett–Garg inequalities are theoretical tools designed to test whether macroscopic systems—like large objects or complex quantum states—can behave according
Bell’s Theorem: Quantum Entanglement Defies Local Realism
Bell’s Theorem, formulated by physicist John Bell in 1964, is a landmark result in quantum physics that shows no theory
Quantum Zeno Effect: Watching Stops the Change
The Quantum Zeno Effect is a counterintuitive phenomenon in quantum mechanics where frequent observation of a system can prevent it
