With reference to Aircraft Systems Mechanical, electrical, and avionics subsystems integration.

As the aircraft speed increases the aerodynamic load increases in a mathematical relationship proportional to the air density and the square of velocity.

What does the above statement mean in layman's terms? Consider explaining it to a high school student.

Also, what's the simplest explanation for the drag formula too?

Fd=1/2 *Density *Velocity^2 *Coeff. drag *Area
