a-=v^2/R
a-=(dv/dt)*T-+(v^2/R)*N-

OP=-R*Un

v-=dOP-/dt=dx(t)/dt.i+dy(t)/dt.j+dz(t)/dt.k
vx(t)=dx(t)/dt=x(t)
vy(t)=dy(t)/dt=y(t)
vz(t)=dz(t)/dt=z(t)

a-(t)=dv-(t)/dt=dvx(t)/dt.i+dvy(t)/dt.j+dvz(t)/dt.k
ax(t)=dvx(t)/dt=d^2x(t)/dt^2=vx(t)=x(t)
ay(t)=dvy(t)/dt=d^2y(t)/dt^2=vy(t)=y(t)
az(t)=dvz(t)/dt=d^2z(t)/dt^2=vz(t)=z(t)

a=v^2/R*Un-+dv/dt*Ut

acceleration normale= v^2/R
acceleration tangentielle= dv/dt
