👆Ni dalam bahasa melayu🙈

Maafler kalau silap pakai terms ke apa sbb sy google translate je 🤣

And tolong tegur auu if ada apa2 nk kena ubah

💡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

📡Chapter 3 - Gravitation
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

Korang sukaaa ehh sy jadikan perkataan² tu spoiler?🤭🤣

Okay lepasni kalau buat lagi important definitions gitu, nnti min Heera buat spoiler😆🤣

InshaAllah

Tajuk f4 apa lagi korg nak min Heera buat important definitions?

Cer bagitau dlm komen🙈

Korang masuk je mana2 quiziz nanti ok..sebab link di buka serentak

Tepat jam 10 malam

Chapter 6 form 4

☆Fizik form 4 Gerakan Jatuh Bebas (2.3)


Definisi :Objek itu jatuh disebabkan oleh daya graviti atau pecutan graviti saja.

💥Rintagan udara diabaikan

💥Masa jatuh bebas tidak bergantung pada :
~jisim objek
~saiz objek
~bentuk haluan [ garis lurus atau parabola ]

💥Masa untuk jatuh bebas dipengaruhi oleh ( faktor) :
~tinggi dari mana objek jatuh
~nilai pecutan graviti

💥Persamaan linear yang digunakan untuk selesaikan masalah [ gantikan a-pecutan kepada g-graviti ]
1) s=ut + 1/2 gt²
2) v=u + gt
3) v²=u² + 2gs

💥Nilai pecutan graviti Bumi adalah 9.81m/s²

🎈Nilai g positif apabila objek bergerak ke bawah (9.81 m/s²)
🎈Nilai g negatif apabila objek bergerak ke atas (-9.81 m/s²)


🎈🎈 pastikan baca soalan betul² sama ada objek tu bergerak ke atas atau ke bawah 👍

Kalau soalan tanya ( contoh )
◇"Apakah yang akan terjadi kepada gerakan roket apabila bergerak ke atas ? "
Jawapan 👉 nyahpecutan/ halaju berkurang
Sebabnya ialah roket melawan daya graviti

◇Kalau dia tanya bergerak ke bawah
Jawapan👉 pecutan / halaju bertambah
