We know the following basics.

Velocity(V) = (Change in Distance)/(Time)

Accelaration(a) = (Change in Velocity)/(Time)


Change in distance is denoted by 'y' and time is represented by 't'.

`V = (dy)/dt`

`a = (dV)/dt = (d(dy/dt))/dt = (d^2y)/(dt^2)`


`a = (d^2y)/(dt^2)`


So finally;

y = represent distance/displacement which is a vector

t = time

d = this means the derivative. This is used to represent the change of velocity and displacement with time.
