New Class-11 Physics | Mass-Energy equivalence | Physics Pulse

Mass-energy equivalence, described by Einstein's famous equation E = mc², means mass and energy are interchangeable forms of the same thing, where a tiny bit of mass holds immense energy because it's multiplied by the speed of light squared ( c). This concept revolutionized physics by showing they aren't separate but convertible, forming the basis for nuclear power, understanding stars, and particle physics, with mass converting to energy (like heat/light) in nuclear reactions, and vice versa. Key Concepts: • E = mc²: Energy (E) equals mass (m) times the speed of light (c) squared. • Interchangeability: Mass can become energy, and energy can become mass, showing they are different manifestations of the same physical reality. • Rest Energy: Even a stationary object has intrinsic energy (rest energy) equal to its mass times 𝑐2 Examples & Applications: • Nuclear Fission & Fusion: In nuclear reactions, a small loss of mass results in a massive release of energy (e.g., nuclear power, atomic bombs). • Particle Physics: Particle-antiparticle annihilation converts their mass entirely into energy (photons), while energy can create particle-antiparticle pairs. • Stars: Stars shine because of continuous mass-to-energy conversion through nuclear fusion. #relativity #einstein #frame_of_reference #inertial #noninertial #theory #quatumphysics #pauli #dirac #particle_physics #sajid #wattoo #atom #historyofatom #physics #1styear #11thclass #newbookptb #sahiwalboard #guesspaper2025 #sahiwalboard #importantShortQuestions #baluchistamBoard #LahoreBoard #ptbNewSyllabus #9thPhysics #10thPhysics #Mcqs #exerciseShortQuestions #NewSyllabus2025 #physicsPulse #MuhammadSajidPhysics #SajidWattooPhysics #PhysicsWallah #alliedSchoolLecture #BeaconHouseSchool #CitySchool #grammerSchool #sahiwalboard #importantphysics #aphadecay #betadecay #gammadecay #excitedstate #nuceartransmutation #radiation #alpha #beta #gamma #chapter12 #shortQuestions #newphysics_Exercise #ch12 #fundamentalparticles #quarks #laptons #leptons #hadrons #baryons #mesons #gluons #gravitons #bosons #fermions #timedilation #lengthcontraction #SIMULTANEITY #REATIVITY
