Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.
Pit lane at Pocono Raceway In any racing series that permits scheduled pit stops, pit strategy becomes one of the most important features of the race; this is because a race car travelling at 100 miles per hour (160 kilometres per hour) will travel approximately 150 feet (45 metres) per second. During a ten-second pit stop, a car's competitors will gain approximately one-quarter-mile (450 ...
British Railway Class 90 infobox showing brake force Brake force to weight ratio of the Class 67 is higher than some other locomotives. In the case of railways, it is important that staff are aware of the brake force of a train so sufficient brake power will be available to bring the train to a halt within the required distance from a given speed.
The values of stopping sight distance used in design represent a near worst-case situation. For design, a conservative distance is needed to allow a vehicle traveling at design speed to stop before reaching a stationary object in its path. A generous amount of time is given for the perception-reaction process, and a fairly low rate of ...
The car and driver must together weigh at least 798 kg as of 2024. [2] The car must only have four wheels mounted externally of the body work with only the front 2 steered and only the back 2 driven. The maximum distance allowed between the front and rear wheels (the wheelbase) is 360 cm.
A modern Formula One car capable of developing up to six G of lateral cornering force and a downforce equivalent to twice its weight at 190 km/h (120 mph). [65] [66] The car is designed to create the maximum amount of downforce for the minimal amount of drag with the configuration often modified to the requirements of a particular track. [58]
A car used by a driver if they have damaged their main car. It may or may not have the same setup as the primary car. Now banned in Formula One for cost-cutting reasons, though teams in many other major racing series have a spare car available at the track. At Indianapolis, it is traditionally called a T-car (a loose abbreviation of "training").
Although KERS was still legal in Formula 1 in the 2010 season, all the teams had agreed not to use it. [38] New rules for the 2011 F1 season which raised the minimum weight limit of the car and driver by 20 kg to 640 kg, [39] along with the FOTA teams agreeing to the use of KERS devices once more, meant that KERS returned for the 2011 season.
