  5. Slip (vehicle dynamics) - Wikipedia

    en.wikipedia.org/wiki/Slip_(vehicle_dynamics)

    In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).

    The other component is the reaction distance, which is the product of the speed and the perception-reaction time of the driver/rider. A perception-reaction time of 1.5 seconds, [ 2 ] [ 3 ] [ 4 ] and a coefficient of kinetic friction of 0.7 are standard for the purpose of determining a bare baseline for accident reconstruction and judicial ...

  7. Velocity - Wikipedia

    en.wikipedia.org/wiki/Velocity

    The general formula for the escape velocity of an object at a distance r from the center of a planet with mass M is [12] = =, where G is the gravitational constant and g is the gravitational acceleration. The escape velocity from Earth's surface is about 11 200 m/s, and is irrespective of the direction of the object.

  8. International roughness index - Wikipedia

    The IRI sensitivity is focused on wavelengths between 0.82 and nearly 200-feet (0.25 to 61 meters). Although, if any wavelengths are equal to 7.9 or 50 feet (2.4 or 15.2 meters) the IRI values are weighted higher. [2] The quarter car model has higher correlations to light trucks and heavy trucks.

  9. Slip ratio - Wikipedia

    en.wikipedia.org/wiki/Slip_ratio

    Slip ratio is a means of calculating and expressing the slipping behavior of the wheel of an automobile.It is of fundamental importance in the field of vehicle dynamics, as it allows to understand the relationship between the deformation of the tire and the longitudinal forces (i.e. the forces responsible for forward acceleration and braking) acting upon it.
