The Risks of Velocity
We see it all over the place from sports activities like NASCAR to video video games to motion pictures like The Quick and Livid and even on our native highways. Individuals, particularly male youngsters, have this want for pace however why do folks like to go quick and what are the potential penalties?
In our want it now society, folks need to get issues carried out rapidly however there’s extra to it than that. Individuals don’t leap out of airplanes or take part in avenue races as a result of they need to arrive at their vacation spot sooner. They do it due to the frenzy they get. Once you pace, your physique releases pleasurable chemical compounds into your physique akin to dopamine and adrenaline. Many excessive athletes require bigger thrills to acquire these chemical compounds or can solely get hold of them solely by way of excessive actions. Nevertheless, this want for pace extends past the racetrack into our on a regular basis actions.
Velocity Kills:
In line with The U.S. Division of Transportation, 32,719 folks died in motorized vehicle crashes in 2013. These deaths will be attributed to many issues together with pace. In a 1999 research, it was discovered that 30% of deadly crashes had been as a consequence of rushing. This could account for about 9,800 deaths in 2013 alone. In 1974, The U.S. Congress established a nationwide pace restrict of 55 mph (89 km/h), which led to a 16% lower in site visitors fatalities. Additional research have proven that a rise of 1 km/h (0.62 mph) above the pace restrict will improve your likelihood of accidents by 3%.
Not solely does rushing trigger extra accidents, rushing additionally will increase the severity of the accident. Accidents change into extra extreme and deaths extra prevalent. This improve is instantly associated to the power exerted on you (and the particular person or object you collide with) throughout a crash and the speed at which you decelerate upon affect.
Additionally be aware that rushing doesn’t merely imply exceeding the posted restrict. Extra pace can even imply touring too quick for circumstances akin to snow, rain, ice or fog. These circumstances hinder your capacity to cease and subsequently, you could journey at a slower tempo.
This studying is one among seven stations included in my One and Two-Dimensional Movement lab station exercise. Within the full model, this studying contains 4 comprehension questions and solutions.

The Science of Velocity
Secure Driving:
It’s easy physics, the sooner your automotive is transferring, the much less time it’s a must to react. In case you are touring at 100 km/h (62 mph) and the item in entrance of you (say a automotive or a tree) is 50 m (164 toes) away, you’ll have 50/27.7 = 1.8 sec to cease earlier than you collide. When you had been going 200 km/h (124 mph), you’d have half the time (0.9 seconds) and so forth. This data will be discovered utilizing the equation – time = distance / pace. Because the common human response time (time earlier than you already know what’s happening) is 0.25 seconds and the automotive takes a sure period of time to return to a cease (1-3 seconds relying in your pace); the sooner you go, the much less seemingly you might be to cease. Moreover, whenever you journey sooner, you require a larger deceleration as a way to gradual you down in the identical period of time. The sooner you decelerate, the extra power is that required to cease you (Power = mass x acceleration). Extra power means extra affect on you and doubtlessly, extra damage particularly if that power is from a tree.
The Three-Second Rule:
Not only for dropped meals anymore. The three-second rule implies that you must have three seconds to cease if wanted. To make sure this, watch the motive force in entrance of you as they cross an object like a phone pole, and so forth. and depend how lengthy it takes you to cross the identical object with out adjusting your pace. If it takes lower than three seconds then you might be following too shut.
