Newton’s Laws of Motion: Explained with Real-Life Examples

  Sir Isaac Newton's   Three Laws of Motion   (published in 1687) revolutionized physics by explaining how objects move. These laws govern everything from   falling apples to rocket launches —making them essential for   science students, competitive exams (JEE, NEET, SSC), and everyday understanding . This guide covers: ✔  Newton’s 3 Laws  (Simple Definitions + Formulas) ✔  Real-Life Examples  (Sports, Vehicles, Space) ✔  Common Misconceptions ✔  Practice Questions By the end, you'll see how these 300-year-old laws apply to your daily life! 📜 Newton’s Three Laws of Motion Law Statement Formula First Law (Inertia) An object remains at rest/moves at constant velocity unless acted upon by a net force. *F_net = 0 ⇒ a = 0* Second Law (F=ma) Force equals mass times acceleration. F = m × a Third Law (Action-Reaction) For every action, there’s an equal and opposite reaction. F₁₂ = −F₂₁ 🚀 Law-wise Explanation + Examples 1. First Law (Law o...

Acids, Bases, and Salts: Definition, Properties, and Uses

  Acids, bases, and salts   are fundamental substances in chemistry that affect everything from digestion to industrial processes. Understanding their properties is crucial for   science students, competitive exams (NEET, JEE, SSC), and everyday life . This article covers: ✔  Definitions & Examples ✔  Physical & Chemical Properties ✔  pH Scale & Indicators ✔  Uses in Daily Life & Industry ✔  Neutralization Reactions By the end, you'll clearly distinguish between acids, bases, and salts—essential for  class 10 NCERT, lab work, and real-world applications . 🔬 Definitions & Examples Category Definition Examples Acids Substances that release  H⁺ ions  in water, taste sour. HCl, H₂SO₄, Citric Acid (lemon) Bases Substances that release  OH⁻ ions , feel slippery, taste bitter. NaOH, KOH, Baking Soda Salts Formed when acids + bases react (neutralization), ionic compounds. NaCl, CaSO₄, KNO₃ 📌 Properties of Acids, B...
