UNIVERSAL GRAVITATIONAL LAW: fg=g*(m1*m2/r2)

g=6.67*10-11     fg=gravitational force    m1/m2=mass of the bodies(kg)     r=distance separading them(m)              Ecuacion

gravity ecuation: g=g*(m/r2)                earth gravity=9.8m/s2

centrifugal force(fcf): m*(v2/r)              v=derecha


INTERACTION BETWEEN ELECTRIC CHARGES (coulombus law)

fe=k*(q*q/d2)    fe=electrical force of attraction or repulsion(n)

k=9*109       q/q=values of each charge(coulombus/c)

d=distance between charges(m)
