EQUATIONS OF MOTION (suvat)

 

NB: THESE EQUATIONS CAN ONLY BE USED IF / WHEN ACCELERATION IS CONSTANT.

 

 

 

NB: be VERY careful to decide which direction is positive

where

s = displacement           (m)      

u = initial velocity           (m/s)

            v = final velocity             (m/s)

            a = acceleration             (m/s²)

            t = time                         (s)

 

Always list all the information BEFORE starting any question

 

·         Positive answers indicate motion in the positive direction

·         Negative answers indicate motion in the negative direction
