Waec formulas for physics

Here are some common WAEC physics formulas:

Mechanics

• Velocity: v = d/t (velocity = distance / time)
• Acceleration: a = (v - u) / t (acceleration = (final velocity - initial velocity) / time)
• Distance (uniform acceleration): s = ut + (1/2)at² (distance = initial velocity × time + one-half × acceleration × time squared)
• Distance (uniform acceleration): v² = u² + 2as (final velocity squared = initial velocity squared + 2 × acceleration × distance)
• Force: F = ma (Force = mass × acceleration)
• Momentum: p = mv (momentum = mass × velocity)
• Impulse: F = m(v - u) (Impulse = change in momentum)
• Work: W = Fd (Work = Force × distance)
• Energy (Kinetic): KE = (1/2)mv² (Kinetic Energy = one-half × mass × velocity squared)
• Energy (Potential): PE = mgh (Potential Energy = mass × gravity × height)
• Power: P = W/t (Power = Work / time)
• Density: ρ = m/V (density = mass / volume)
• Pressure: P = F/A (Pressure = Force / Area)

Heat

• Specific Heat Capacity: Q = mcθ (Heat = mass × specific heat capacity × temperature change)
• Latent Heat: Q = mL (Heat = mass × specific latent heat)

Waves

• Wave Speed: v = fλ (Wave speed = frequency × wavelength)

Electricity

• Current: I = Q/t (Current = charge / time)
• Ohm's Law: V = IR (Voltage = Current × Resistance)
• Resistance in Series: R_total = R₁ + R₂ + ...
• Resistance in Parallel: (1/R_total) = (1/R₁) + (1/R₂) + ...
• Power: P = VI = I²R = V²/R (Power = Voltage × Current = Current squared × Resistance = Voltage squared / Resistance)
• Charge: Q = ne (Charge = number of electrons × elementary charge)

Modern Physics

• Energy of a Photon: E = hf (Energy = Planck's constant × frequency)
