Kinematic Equations

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Kinematics formulas are about objects in motion and their interrelationship.  These formulas are only accurate if acceleration is constant during a time interval and it assumes all variables are in the same direction.

 

Formulas that use Kinematic Equations

\(\large{ d = v_i \; t + \frac {1} {2} \; a \; t^2 }\)   
\(\large{ \frac {v_i \;+\; v_f} {2} = \frac {d} {t} }\)  
\(\large{ a = \frac {v_f \;-\; v_i} {t} }\)   
\(\large{ {v_f}^2 = {v_i}^2 + 2 \; a \; d }\)  

Where:

\(\large{d}\) = displacement

\(\large{a}\) = acceleration

\(\large{t}\) = time

\(\large{v_f}\) = final velocity

\(\large{v_i}\) = initial velocity
