So I derived this equation for the net force/acceleration of a motorcycle on a flat surface. I beleive this equation could practically be used for any rolling object.(adsbygoogle = window.adsbygoogle || []).push({});

ƩF = F_{p}- μ*F_{n}- F_{D}

Where: F_{P}is the force of the bike acting against the ground, tangent to the ground

F_{D}= [itex]\frac{1}{2}[/itex]pv^{2}C_{D}A (air drag)

μ*F_{n}is the frictional force of the tires, F_{n}is the normal force.

Now to find a:

ma = F_{p}- μF_{n}- F_{D}

a = (F_{p}- μF_{n}- F_{D}) / m

Is there anything wrong with this?
