In physics , the fourth, fifth and sixth derivatives of position are defined as derivatives of the position vector with respect to time — with the first, second, and third derivatives being velocity , acceleration , and jerk , respectively. However, these higher-order derivatives rarely appear,  and have little practical use, thus their names are not as standard. The fourth derivative is often referred to as snap or jounce. The name "snap" for the fourth derivative led to crackle and pop for the fifth and sixth derivatives respectively,  inspired by the advertising mascots Snap, Crackle, and Pop. Snap ,  or jounce , is the fourth derivative of the position vector with respect to time , or the rate of change of the jerk with respect to time.
'Don't Jerk And Drive' Campaign Pulled
Researchers Discover Why Drivers Jerk Steering Wheels Inexplicably - The News Wheel
I drive a 94 acura integra The other day I was driving and out of no where my steering wheel was jerking left to right hard. It was hard just to keep the wheel straight I didn't drive for long I pulled over as soon as it happened and haven't driven it since. Does anyone know what this could? I couldnt really hear any noises but then again I was panicking. I was thinking maybe a ball joint or control arm? Any suggestions would he awesome.
JERK THE WHEEL
Unfortunately for the South Dakota office of Highway Safety, some people think their new safe-driving campaign around the slogan "don't jerk and drive" was a bad idea. The ad campaign, intended to keep people from over correcting and jerking their steering wheels in icy conditions, struck some as offensive because of its allusion to masturbation. One of the critics, according to the paper, was state Rep. Mike Verchio who planned to ask the department what it was thinking before the TV commercials and social media promotions were yanked. The Highway Safety office insists the double entendre was intentionally inserted to get people's attention.
However, sometimes car jerks when accelerating is a common problem faced by several car owners. You must be aware of all the feasible reasons behind the problem in accelerating before jumping to the solution. The car jerking problem happens to be an issue common in both manual and automatic cars. What does it mean when your car jerks? Air filters keep the car away from the road pollutants such as dirt, debris and other things that contaminate the engine.
