📘 GCSE Physics Formula Sheet

All essential physics formulas with examples to help your revision! ✅ From forces to electricity, energy, waves, and more — this complete formula guide is perfect for exam prep.

🧲 Forces

• Force: F = m × a
  Example: F = 2 × 3 = 6 N
• Weight: W = m × g
  Example: W = 10 × 9.8 = 98 N
• Work Done: W = F × d
  Example: W = 5 × 10 = 50 J
• Momentum: p = m × v
  Example: p = 4 × 2 = 8 kg·m/s
• Pressure: p = F / A
  Example: p = 20 / 5 = 4 Pa

🔋 Energy & Power

• Kinetic Energy: KE = ½ × m × v²
  Example: KE = ½ × 3 × 4² = 24 J
• Gravitational Potential Energy: GPE = m × g × h
  Example: GPE = 5 × 9.8 × 10 = 490 J
• Power: P = E / t
  Example: P = 100 / 5 = 20 W
• Efficiency: (Useful Output / Total Input) × 100
  Example: (80 / 100) × 100 = 80%
• Specific Heat Capacity: E = m × c × ΔT
  Example: E = 2 × 4200 × 5 = 42000 J
• Latent Heat: E = m × L
  Example: E = 1.5 × 334000 = 501000 J

⚡ Electricity

• Charge Flow: Q = I × t
  Example: Q = 3 × 10 = 30 C
• Potential Difference: V = I × R
  Example: V = 2 × 5 = 10 V
• Energy Transferred: E = Q × V
  Example: E = 10 × 5 = 50 J
• Alt. Energy Transferred: E = P × t
  Example: E = 100 × 10 = 1000 J

🌊 Waves

• 📡 Wave Speed: v = f × λ
  Example: v = 50 × 2 = 100 m/s

⚖Density

• Density: ρ = m / V
  Example: ρ = 12 / 3 = 4 kg/m³
