Question

In order for the bug to fly through the air a force has to push the bug forward. Identify this force. How does the bug produce

Answer 1

While a bug fly in the air the weight of bug is counter balanced by the buoyancy force that is applied by air on the bug

This buoyancy force is net upthrust on the bug due to air which will help the bug to float in the air

This buoyancy force is given by the formula

$F_b = \rho V g$

here we know that

$\rho$ = density of air

V = volume of bug

so here we can say that upthrust of air is the force that bug will experience during his uplift
