Today I learned about the four forces of rocket technology. The four forces are:
Thrust: the rocket fuel burning to boost the rocket upwards.
Drag: The air pushing down on the rocket, trying to slow it down.
Lift: Bernoulli’s principle working to create lift, boosting the rocket upwards.
Weight: the gravity pulling the rocket back down to earth.
Bernoulli’s principle is the rule that is explained through F.L.P. S.H.P.
F.L.P. S.H.P. is short for flip the ship which is an abbreviation to the general idea of Bernoulli’s principle. F.L.P. is short for Faster the velocity, the Lower the Pressure. S.H.P. is the opposite which is Slower the velocity, the Higher the Pressure.
Bernoulli’s principle helps a plane fly because having a lower pressure underneath the wing, combined with the higher velocity of the air currents going over create lift. This is how a plane flies.
in class we made tumble gliders which use these rules to stay airborne using only a piece of cardboard to steer.
