Distance, speed and time in words

Speed(m/s) = Distance(m)/time(s)

Distance, speed and time in letters

v=s/t

Acceleration in words

Acceleration(m/s2)= change in speed(m/s)/time taken(s)

Acceleration in letters

a=v-u/t

Equation of motion

v2 = u2 + 2as

Force in words

Force(N) = Mass(kg) x acceleration(m/s2)
