Could be bad u-joints in the driveshaft.
An object that is accelerating may be slowing down, gaining speed, and changing direction.
the wineing is probably the fuel injecters because that is what was wrong with my dads truck.
No, when anything is slowing down it is decelerating.
In physics, "acceleration" means there is a change of velocity.
It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
It depends on where the sound seems to be coming from, but worn brake pads are an option.
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
One tire has a belt separation.
No. Negative acceleration simply means it is accelerating in a particular direction.
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
Yes it has negative acceleration, which is acceleration in the opposite direction of travel. It is called deceleration.
Could be a turbocharger, or a low oil level in a manual transmission causing it to "howl".
