Rocket Science

Today I learned about the four forces of rocket technology. The four forces are:

  • thrust
  • drag
  • lift
  • weight/gravity


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.
