📦 Spring Balance (10 N)
Neraca spring digunakan untuk mengukur daya atau berat. Bacaan biasanya dinyatakan dalam unit newton (N).
A spring balance is used to measure force or weight. The reading is usually given in newtons (N).
👀 Cara Membaca | Reading Technique
✅ Gantungkan objek secara menegak dan tunggu sehingga penunjuk berhenti bergerak.
✅ Hang the object vertically and wait for the pointer to become steady.
✅ Baca skala pada paras mata untuk mengelakkan parallax error.
✅ Read the scale at eye level to avoid parallax error.
✅ Pastikan bacaan diambil pada skala Newton (N) yang betul.
✅ Ensure the reading is taken from the correct Newton (N) scale.
✅ Semak nilai bahagian terkecil (least count) sebelum merekod bacaan.
✅ Check the smallest division (least count) before recording the reading.
❌ Common Mistakes
❌ Membaca skala dari sudut serong.
❌ Reading the scale from an angle.
❌ Mengambil bacaan ketika objek masih berayun.
❌ Taking readings while the object is still swinging.
❌ Mengelirukan unit N dengan gf (gram-force).
❌ Confusing N with gf (gram-force).
❌ Tidak menyemak sama ada penunjuk berada pada sifar sebelum digunakan.
❌ Failing to check whether the pointer is at zero before use.
⚠️ Safety / Handling
⚠️ Jangan melebihi had maksimum 10 N.
⚠️ Do not exceed the maximum capacity of 10 N.
⚠️ Elakkan menjatuhkan neraca spring kerana spring di dalamnya boleh rosak.
⚠️ Avoid dropping the spring balance as the internal spring may be damaged.
⚠️ Simpan dalam keadaan tergantung atau tegak selepas digunakan.
⚠️ Store the spring balance upright after use.
🎯 SPM Exam Tip
📌 Spring balance measures force, not mass.
📌 Neraca spring mengukur daya, bukan jisim.
📌 Unit SI bagi daya ialah Newton (N).
📌 The SI unit of force is Newton (N).
📌 Berat objek boleh dikira menggunakan:
📌 Weight of an object can be calculated using:
W = mg
where:
- W = Weight / Berat (N)
- m = Mass / Jisim (kg)
- g = Gravitational field strength / Kekuatan medan graviti (≈ 9.81 N kg⁻¹)

🧠 Did You Know?
🪝 Spring balances work based on Hooke's Law.
🪝 Neraca spring berfungsi berdasarkan Hukum Hooke.
📌 The extension of the spring is proportional to the applied force, provided the elastic limit is not exceeded.
📌 Pemanjangan spring berkadar terus dengan daya yang dikenakan, selagi had keanjalan tidak dilebihi.
