Geachte Professor dr. ir.,
Een raket motor levert een constante kracht F_constant.
Deze kracht wordt opgevangen door de raket (inclusief de motor) en de brandstof.
Stel nu dat de massa van de raket m_raket = m0 + p1 t
waarbij m0 de rust massa van de raket (inclusief de motor) is
en p1 de verbruikte brandstof per seconde is
en t de tijd is in seconden.
Er is dan een veranderende snelheid per seconde, die niet gelijk aan nul is.
de da/dt <>0 waarbij a de versnelling is.
Is deze conclusie correct?
Groet Simon Boersen

Dear Professor dr. ir.,
A rocket engine delivers a constant force F_constant.
This force is absorbed by the rocket (including the engine) and the fuel.
Now suppose the mass of the rocket m(t) = m0 + p1 t
where m0 is the resting mass of the rocket (including the engine)
and p1 is the fuel used per second
and t is the time in seconds.
There is then a changing speed per second, which is not equal to zero.
the da / dt <> 0 where a is the acceleration.
Is this conclusion correct?
Regards Simon Boersen
