There is a lot of maths in toys, mathspigs. Just look at the equation for AERODYNAMIC DRAG (below). Scientists and engineers use equations like this to design techno toys.

D = Drag Force [Newton] …………………………………………………………….
ρ = density of the fluid…………………………………………………………….
v = velocity of plane or car.……………………………………………………………
A = front X-section Area of the car/plane (A can be a simple X-section Area or a more complex surface area depending on the design.)………………………
Cd = drag coefficient (A constant determined by experiment)
Passenger car Cd = 0.30 – 0.35…………………………………………………………….
SUV Cd = 0.35 – 0.45 (Flat front)………………………………………………..
Sport cars Cd = 0.25…………………………………………………………….
Toyota Prius 2004 Hybrid Cd = 0.26 ………………………………………………….
Toyota Prius 2004 Hybrid

Area (A) for Prius
.
Drag D Vs Speed or velocity v
As drag increases with the square of velocity, you can see from the graph how quickly it increases for any object.
