This simulation uses Newton's Laws of Physics to calculate all forces acting on the vehicle.

Negative Forces: Air Resistance and Rolling Resistance

Positive Forces: Wheel Force provided by motor(s)

F_d = {1\over2}ρ{v}^2C_dA

The force acting opposite to the relative motion of any object moving with respect to a surrounding fluid (air).

Unlike other resistive forces, air resistance depends on velocity.

Air Density ( $ρ$ )

Mass per unit volume of Earth's atmosphere with units $kg/m^3$

Velocity ( $v$ )

How fast the vehicle is moving (speed) with units $m/s$

Coefficient of Drag ( $C_d$ )

Dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment

Frontal Area ( $A$ )

Reference Area or cross-sectional area of vehicle perpendicular to velocity vector with units $m^2$

F_{rr} = C_{rr}N

The force resisting the motion when a tire rolls on a surface.

It depends on many factors including tire compound, width, inflation pressure, and more.

Coefficient of Rolling Resistance ( $C_{rr}$ )

Force needed to push a wheeled vehicle forward (at constant speed on a level surface with zero grade and air resistance) per unit force of weight

Normal Force ( $N$ )

Weight of the object: $F_n=mg$ where $m$ is mass and $g$ is the gravitational field strength (about $9.806 m/s^2$ on Earth)
