3. Dynamics and Handling
- Newtonian Dynamics: Longitudinal acceleration a = F_traction / m. Lateral acceleration (cornering) a_lat = v^2 / r; maximum a_lat limited by tire friction μ and vertical load: F_lat_max ≈ μ·N.
- Weight Transfer: Under acceleration/braking/turning, weight shifts: ΔN = (F·h)/b for longitudinal, where h = CG height, b = wheelbase. More weight on driven wheels increases traction but can increase understeer/oversteer tendencies.
- Understeer/Oversteer: Balance between front/rear lateral grip. Suspension geometry, roll stiffness distribution, and tire choices tune handling characteristics.
- Suspension Basics: Spring rate sets ride frequency; damping controls transient oscillations. Anti-roll bars redistribute load during cornering. Lower center of gravity reduces weight transfer and improves handling.

- Tractive force F = Tw / r = 2400 / 0.3 = 8000 N.
- Theoretical acceleration a = F/m = 8000 / 1200 ≈ 6.67 m/s^2 (≈ 0–60 mph in ~4.3 s ignoring losses, gear shifts, and aerodynamics).
