The braking distance at 70mph is a huge 75m, which is about 9 London buses. FACT: get something wrong and people get hurt. Deceleration has actually referred to the acceleration in a reverse way. This resource is designed for UK … 3.6 = fixed figure for converting km/h to m/s. Stopping Times: The physics of stopping a moving vehicle - such as a bike or car - is vitally important every day. Source:en.wikipedia.org . With an increase in mass, the braking distance of a car a) Increases b) Decreases c) Stays the same d) Goes up and down . Stopping distances are a favourite part of … Specification reference GCSE Combined Science: Synergy; Outcome 6 : Speed is measured by the distance travelled in a certain time. This stopping distance formula does not include the effect of anti-lock brakes or brake pumping. The final velocity, v f = 0 m/s. OCR A. OCR B. WJEC. Thus acceleration means the rate at which an object speeds up, deceleration means the rate at which an object slows down. Preview and details Files included (1) pptx, 5 MB.

For example, if you answer a question about braking distance, thinking you are answering a question about stopping distances, you’ll inevitably get the wrong answer. These are equally helpful to prepare for other boards and competitive examinations of different countries. For related links and resources, visit the download page for this resource at skillsworkshop. The total stopping distance = thinking distance + braking distance. 1. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, and negligibly by the tires' rolling resistance and vehicle's air drag. Stopping distance is the total distance needed to bring your vehicle to a complete stop. BRAKING DISTANCES. Info.
