Question

Hello Friends


Derive the first equation of motion Mathematically

Answer 1

Hey!!!!


First Equation Of Motion:


v= u+at


Derivation:

${accl}^{n} = \: \: \frac{change \: in \: velocity}{time \: taken}$
${accl}^{n} = \frac{final \: velocity - initial \: velocity}{time \: taken}$
$a = \frac{v - u}{t}$
${at} = {v - u}$
$by \: transposing \: \: \: t \: \: \: to \: lhs$
$u + at = v$
$(by \: transposing \: \: \: u \: \: \: to \: lhs$


v=u+at



#BE BRAINLY

Answer 2

a=change in time/change in velocity a=BD/AD=BD/OC=BD/t BD=at(eq.1) BC=BD+DC BC+AO v=BE+u BD=v-u(equal.2) From 1 and 2 we get  v-u=at So,at=v-u Thanks.
