🌍 Gravitation – Lecture Description (With Keywords) 📘 Introduction Gravitation is the natural force of attraction between any two objects in the universe. It is the force that keeps us on Earth, controls the motion of the Moon around the Earth, and keeps planets in orbit around the Sun. The law of gravitation was proposed by Isaac Newton in 1687. 🔑 Important Keywords in Gravitation Lecture Gravitation Gravity Force of Attraction Universal Law of Gravitation Inverse Square Law Mass (m₁, m₂) Distance (r) Gravitational Constant (G) Acceleration due to Gravity (g = 9.8 m/s²) Free Fall Weight (W = mg) Orbit Gravitational Field Tides Satellite Motion 📖 Key Concepts Explained Briefly 1️⃣ Universal Law of Gravitation Every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. Formula: 2️⃣ Acceleration Due to Gravity (g) Value on Earth: 9.8 m/s² Acts downward toward the center of the Earth Responsible for free fall motion 3️⃣ Mass vs Weight Mass → Amount of matter (constant everywhere) Weight → Force due to gravity (changes with location) 4️⃣ Applications of Gravitation Motion of planets Satellite launching Ocean tides Falling objects If you want, I can also provide short notes, long answer format, or numerical problems with solutions for exam preparation.
