প্রমাণ করতে

\sf\;S=ut+\frac{1}{2}at^2\\

ব্যাখ্যা:-

আমরা জানি যে

\sf\;Displacement=Average\;velocity\times time\\\\Average\;velocity=\frac{u+v}{t}\\\\S=\frac{u+v}{t}\times t\\(S=displacement)\\\\From\;1st\;equation\;of\;motion\;v=u+at\\\\s=\frac{u+u+at}{2}\times t\\\\s=\frac{2u+at}{2}\times t\\\\s=\frac{2ut+2at^2}{2}\\\\s=\frac{2ut}{2}+\frac{at^2}{2}\\\\\boxed{\bold{S=ut+\frac{1}{2}at^2}}
