Physics: The Big 5 Equations

Vi - initial velocity

Vf - Final velocity

a - acceleration

t - change in time

d - displacement

  1. Vf = Vi + at

  2. d = (Vi+Vf)/2 * t

  3. d = Vi * t + (1/2) at²

  4. d = Vf * t - (1/2)at²

  5. Vf² = Vi² + 2ad

These 5 equations relate the five kinematic variables (d, vi, vf, a, and t) to each other.

As soon as you know 3 kinematic quantities, you can always fine a fourth quantity using the appropriate BIG five!
