COVID19 An energetic analogy




The Total Mechanical Energy

The mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (abbreviated TME)

TME = PE + KE

Analogical models are a method of representing a phenomenon of the world, often called the « target system » by another, more understandable or analysable system. They are also called dynamical analogies.

Kinetic energy KE= 1/2* IA14* Rt*Rt

Incidence IA14 (cases / 100,000 inhab. In the last 14 days)

Speed Rt = ( IA14(t+1)-IA14(t))/t

Potential energy KP=1/2* K* t*t

K is the stiffness to resist to the pandemia

Kinetic energy

    \[    \boxed{KE=\int_0^{\infty}\! (IA14*Ro7) \mathrm{d}t} \]

Example : Spain source https://biocomsc.upc.edu/en/covid-19/Worldcovid-en

IA14 Spain
Risc EPG=IA14*Ro7

Rt
Kinetic energy Phase 2

First days Stiffness K increases till 40 days. After the stiffness decreases, the max is at 40 days. For Spain so the phase2 will be finished at 120 days, first days of December.
