Distance - Wikipedia Straight-line distance is formalized mathematically as the Euclidean distance in two- and three-dimensional space. In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. In a network, during the process of data communication, latency (also known as delay) is defined as the total time taken for a complete message to arrive at the destination, starting with the time when the first bit of the message is sent out from the source and ending with the time when the last bit of the message is delivered at the destination. The circumference of the wheel is 2 radius; if the radius is1, each revolution of the wheel causes a vehicle to travel 2 radians.

(2017, October 11). Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. Following too closely may be defined as, "situations in which one vehicle is following another vehicle so closely that even if the following driver is attentive to the actions of the vehicle ahead he/she could not avoid a collision in the circumstance when the driver in front brakes suddenly." 14 This strategy helps motorists observe roadside landmarks as reference points for two different vehicles using their front and rear-end bumpers as objective spatial cues to cover a safe following distance relative to the speed limit.
