Indeed, when the wheels move forward and then have momentum p\textbf{p}, they achieve the angular momentum:


L=r×p.\textbf{L}=\textbf{r}\times\textbf{p}.

But what does the angular momentum represent? Is it a force? Let's see.

According to the expression, it's measured in units of distance times units of momentum:



kgm2/s,\text{kg}\cdot\text{m}^2/\text{s},

it is not Newton and thus it's not a force. The angular momentum just measures how much inertia a rotating body has. What can make the wheels come out, however, is a force. Forces can produce motion as you correctly mentioned, but what is produced in the described situation is not a force.
