Why would a car jerk during deceleration?
Well if its an automatic, that's easy... I have this too. first answer this...
how fast are you going?
does it have overdrive (auto only)?
if manual what gear you get up to when this happens?
well if its auto, and your going fairly fast and suddenly let go of the gas... its going to change down quite quick due to gearbox design. This would give the sensation of the car braking...
if its a manual car, then you are most likely in too low a gear to start with, this is why we change down when we loose our brakes, speed reduction is effective immedeatly without brakes...it slows you down to save emergency speed...1 min or so.
Answer 1 It means the change in speed is a constant, over the time interval in question. Another view is to plot speed versus time, you would get a straight line with a constant slope. For the geeks, it means the function representing distance versus time is a quadradic (power of 2), so that the second derivative (acceleration) is a constant. For example if the distance versus time is D=3T**2 then the speed at any…
If a car moving at an initial velocity of 19 meters per sec has a stopping distance of 31 meters what is the magnitude of its acceleration?
In a controlled test condition (like crash tests on cars) an accelerometer is used to measure the rate of deceleration. It should be possible to estimate the deceleration following a collision if the speed of the vehicles at the moment of the collision is known. We could do this by measuring the amount the car was crushed/dented during the collision. We know the vehicle decelerated from its starting speed over this distance so we can…
This could be the cause if an improper alignment if it happens under normal straight line driving. If the jerk is more prevalent when going on bumpy roads, it may be a sign of bad shocks or springs. If the jerk is occurring during braking situations, the problem may be related to the bearings being worn or warped discs/drums in the braking system.
If a car going 80 kilometers per hour stops in a distance of 50 meters what is its acceleration in meters per second squared and how many g's is that?
There are a few ways to go about solving this one. Here's one that takes a few steps, but they're easy to follow. What is the average speed of the car during its rapid deceleration? Assuming constant deceleration, it's (80 - 0)/2 = 40 km/s = 11.1 m/s. (I'm playing fast and loose with the signs at this point.) Divide the stopping distance (50 m) by that speed and you get 4.5 seconds. Acceleration, a…
The only difference is in the direction. Acceleration is when you increase your speed, deceleration is when you decrease your speed. Like pressing a gas pedal or brake in a car. In more technical terms, acceleration is parallel to and in the direction of velocity whereas deceleration is parallel and opposite to velocity. In any case, you can always call deceleration "Acceleration in the opposite direction of motion" In physics, both are just called "acceleration".
I had this problem on my 2003 X-type. The first thing you need is have a diagnosis perfomed on the car. The check engine light would go on and off periodically. My car would also hesitate and jerk really badly every time I accelerated suddenly. It turned out to be the oxygen sensor. Costs you about $200.
Why does my air conditioner hiss and jerk the car then blow hot air then jerk and hiss again and then blow cold?
Your A/C compressor is shot. It's internal computer (or that of your car) is malfunctioning. The "jerk" is when your "A/C" kicks in...an A/C compressor takes much of your cars usable power. As it turns on and off you will get the hiss and jerk. (the hiss comes from the overworked compressor lines cooling)
the rapid deceleration from whatever speed the car was doing down to zero in a very quick time and over a miniscule distance causes the arteries connecting our organs to disconnect. eg. the main arteries of the heart disconnecting due to the impact. the human body isn't able to take such deceleration.
