What are the 5 key kinematics equations?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The five essential kinematics equations are:
- v = u + at (velocity-time relation)
- s = ut + ½at² (displacement-time relation)
- v² = u² + 2as (velocity-displacement relation)
- s = (u + v)t / 2 (average velocity relation)
- s = vt - ½at² (alternative displacement formula)
Each equation uses different combinations of the five variables (u, v, a, t, s), allowing you to solve any kinematics problem when three variables are known.
