Question

velocity and time relation : v=u+at :: displacement and time relation​

Answer 1

Answer:

Prove v = u + at  

where u = initial velocity, v = final velocity, a = acceleration and t = time period

Explanation:

Answer

We know acceleration (a) = rate of change of velocity

                                         

                                          =  

timeinterval

changeinvelocity

​

 

                                         

                                          =  

timeperiod

finalvelocity−initialvelocity

   

                                         

                                          =  

t

v−u

​

 

∴a=  

t

v−u

​

ora×t=v−u

or at = v - u or at + u = v

∴ v = u + at
