New Class 11-Physics | Chapter 12 | Four Fundamental Forces of Nature | Physics Pulse | M Sajid

The four fundamental forces of nature are Gravity, Electromagnetism, the Strong Nuclear Force, and the Weak Nuclear Force, governing all interactions in the universe, from holding atoms together to shaping galaxies. Gravity affects mass/energy over vast distances, electromagnetism binds atoms and light, the strong force holds atomic nuclei together, and the weak force governs radioactive decay. Here's a breakdown of each: • Gravity: The weakest force but with infinite range, responsible for attraction between objects with mass, shaping planets, stars, and galaxies. • Electromagnetism: Acts on charged particles, responsible for electricity, magnetism, and light; has infinite range but can be shielded. • Strong Nuclear Force: The strongest force, binding quarks into protons/neutrons and holding the nucleus together; acts over extremely short distances. • Weak Nuclear Force: Responsible for certain types of radioactive decay (like beta decay) and nuclear fusion; also acts over very short distances. #physicsNewbook #nucleus #atomicnumber #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
