GCSE Physics Formula Poster
Forces & Motion
Speed = Distance / Time: v = d / t
Acceleration = Change in velocity / Time taken: a = (v - u) / t
Force = Mass × Acceleration: F = m × a
Weight = Mass × Gravitational field strength: W = m × g
Work done = Force × Distance moved: W = F × d
Momentum = Mass × Velocity: p = m × v
Resultant force = Change in momentum / Time: F = (change in p) / t
Electricity
Potential Difference = Current × Resistance: V = I × R
Charge = Current × Time: Q = I × t
Energy transferred = Charge × Potential difference: E = Q × V
Power = Energy transferred / Time: P = E / t
Power = Current × Potential difference: P = I × V
Power = Current² × Resistance: P = I² × R
Waves
Wave speed = Frequency × Wavelength: v = f × lambda
Energy Resources & Transfers
Kinetic Energy = 0.5 × Mass × (Velocity)²: KE = 0.5 m v²
Gravitational Potential Energy = Mass × g × Height: GPE = m g h
Elastic Potential Energy = 0.5 × Spring constant × Extension²: E = 0.5 k e²
Efficiency = Useful energy output / Total energy input
Work done = Force × Distance: W = F × d
Power = Work done / Time: P = W / t
Solids, Liquids & Gases
Density = Mass / Volume: rho = m / V
Pressure = Force / Area: P = F / A
Pressure in liquids = Density × g × Depth: P = rho g h
Boyle's Law: P1 V1 = P2 V2
Magnetism & Electromagnetism
Force on wire = Magnetic field strength × Current × Length: F = B I l
Radioactivity & Particles
Activity = Number of decays per second (Becquerels)
Astrophysics
Orbital Speed = 2 x pi x Orbital radius / Time period: v = 2 pi r / T
