Suppose there is a falling object that has flaps around it providing resistance to the non-contact force of gravity. How would the vehicle theoretically not flip over?

From my understanding, the flaps provide an upward force on the vehicle causing a net torque of zero. Algebraic explanations would help.

  • $\begingroup$ Flaps don't provide resistance to the force of gravity ... they provide air drag. The direction of the force of air drag is opposite the direction of motion. For objects traveling up, the direction of the air drag force is down, and vice versa. $\endgroup$ – David White Dec 8 '18 at 22:39

Flaps provide aerodynamic (velocity proportional) force. This is not directly related to gravity.

The aerodynamic force can have a net torque resultant different from zero.
