Jebakan ujian fisika
Panduan singkat untuk kesalahan yang memotong nilai. Setiap halaman menampilkan jawaban salah, perbaikannya, dan kalkulator untuk memverifikasi.
Massaa vs Berat Kesalahan yang Mengurangi Nilai
Fix the most common massa vs berat errors: kg as newtons, W dalam F = ma, g = 9.8 vs 10, gaya normal on ramps, and Moon g. Wrong → kanan examples plus free calculators.
SUVAT Sign Kesalahan That Flip Your Jawaban
Fix common SUVAT sign traps: calling all slowing “negative a,” mixing distance with perpindahan, dropping signs dalam v² = u² + 2as, and wrong free-fall directions.
F = ma Kesalahan: Net Gaya vs Berat
Stop using berat as gaya resultan, forgetting gesekan opposite motion, mixing kg with N, and applying F = ma to a single gaya when several act.
Massaa jenis Satuan Kesalahan (g/cm³ vs kg/m³)
Fix massaa jenis traps: mixing grams with m³, treating liters as m³, using benda massaa jenis dalam Fb = ρVg, and forgetting 1 g/cm³ = 1000 kg/m³.
Usaha vs Daya Kesalahan (Joules vs Watts)
Fix usaha vs daya traps: calling watts “usaha,” leaving time dalam minutes, using P = Fv when gaya is not along motion, and mixing mechanical daya with P = VI.
