💡Physics with Heera

📡Chapter 3 - Gravitation
3.1 Newton's Universal Law of Gravitation

Important Definitions !

1⃣ Gravitational Force

👉Known as Universal force
👉Why? It acts between any two bodies in the universe
👉Force of attraction between any two bodies
👉Gravitational force exists between 2 bodies
👉both bodies experience gravitational force of the same magnitude

💥Directly proportional to the product of the masses of the two bodies
💥Inversely proportional to the square of the distance between the centres of the two bodies


2⃣Newton's Universal Law of Gravitation.... states that

🔍 The gravitational force between two bodies is directly proportional to the product of the masses of both bodies
🔍Inversely proportional to the square of the distance between the centres of the two bodies


3⃣Centripetal Force (pg 90)

🌻A force acts on the body in a direction towards the centre of cirlce
🌻The magnitude of the centripetal force depends on the
a) Mass of the body
b) Linear speed
c) Radius of the circle

3.2 Kepler's Law

Important Definitions !

1⃣Kepler's 1st Law

🪐All planets move in elliptical orbits with the Sun🌞 at one focus
🪐Law of Orbits


2⃣Kepler's 2nd Law

👉A line that connects a planet to the Sun sweeps out equal areas in equal times
👉Law of Areas


3⃣Kepler's 3rd Law

⏳The square of the orbital period(T²) of any planet is directly proportional to the cube of the radius(r³) of its orbit
⏳Law of Periods
