Physics Rules & Formulas

Complete guide to velocity, acceleration, and kinematics formulas

Velocity Formulas

Essential velocity equations for physics calculations

Average Velocity

v = Δx / Δt

v = velocity, Δx = displacement, Δt = time interval

Practice Velocity

Speed

s = d / t

s = speed, d = distance, t = time

Practice Speed

Units

m/s, km/h, mph

Common velocity units in physics

Practice Units

Acceleration Formulas

Essential acceleration equations for physics calculations

Average Acceleration

a = Δv / Δt

a = acceleration, Δv = change in velocity, Δt = time interval

Practice Acceleration

Final Velocity

v = v₀ + at

v = final velocity, v₀ = initial velocity, a = acceleration, t = time

Practice Final Velocity

Units
