Penjelasan untuk soalan ini

Apabila gelombang air melalui celah (jurang sempit), gelombang air merebak. fenomena tersebut dikenali sebagai PEMBELAUAN GELOMBANG.

Walau bagaimanapun, panjang gelombang gelombang air kekal tidak berubah selepas ia merambat melalui celah

👆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

📡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🙈

☆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
