Quick Formulas Cheat Sheet

Newton’s Second Law

F = m × a

Force = Mass × Acceleration

Density

ρ = m / V

Density = Mass ÷ Volume

Ohm’s Law

V = I × R

Voltage = Current × Resistance

Ideal Gas Law

PV = nRT

Pressure × Volume = moles × R × Temp

Kinetic Energy

KE = ½mv²

Kinetic Energy = 0.5 × Mass × Velocity²

Molarity (M)

M = n / V

Molarity = Moles of solute ÷ Liters of solution

Work Done

W = F × d × cos(θ)

Work = Force × Displacement

pH Equation

pH = -log[H⁺]

pH = Negative log of Hydrogen ion conc.
