GDP evolution

GDP value
GDP rate of change: (GDP(t)-GDP(t-1))/GDP(t-1)
Speed: GDP(t)-GDP(t-1). Unit is million euro per quarter
Acceleration: GDP(t+1)-2*GDP(t)+GDP(t-1). Unit is million euro per quarter²
Force: GDP(t)*acceleration(t). Unit is million euro² per quarter²
Acceleration 2: acceleration(t)/GDP(t)
Rate of change of GDP rate of change: (GDP(t-1)/GDP(t)).(GDP(t+1)-GDP(t))/(GDP(t)-GDP(t-1))-1
Force2: GDP(t)*RocRoc(t)
