O Level GCE Physics – Complete Formula Sheet
High-contrast • Orange theme • Exam-ready
1. Kinematics
• v = u + at
• s = ut + ½at²
• v² = u² + 2as
• s = (u + v)t / 2
• a = (v − u) / t
2. Dynamics
• F = ma
• Weight, W = mg
• Momentum, p = mv
• Force = ∆p / t
3. Work, Energy & Power
• Work done, W = Fs
• Kinetic Energy, KE = ½mv²
• Gravitational Potential Energy, GPE = mgh
• Power, P = W / t
• Efficiency = (useful output / total input) × 100%
4. Pressure
• Pressure = Force / Area
• Liquid pressure, p = ρgh
5. Thermal Physics
• Heat energy, Q = mc∆T
• Latent heat, Q = mL
6. Waves
• Wave speed, v = fλ
• Frequency, f = 1 / T
7. Light
• Refractive index, n = sin i / sin r
•n=c/v
8. Electricity
• Charge, Q = It
• Potential difference, V = W / Q
• Ohm’s Law: V = IR
• Power, P = VI
• Energy, E = Pt
9. Resistance
• Series: R = R■ + R■
• Parallel: 1/R = 1/R■ + 1/R■
10. Radioactivity
• Half-life: time for activity to halve
