It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
No, when anything is slowing down it is decelerating.
Yes. Acceleration is any change in velocity. When a car slows down it is decelerating; think of deceleration as acceleration in the negative direction.
Could be a small thing like wheels out of balance 40+ "Noisy Inside Car" bad wheel bearings 30+ mph also decelerating harder to control "Steering wheel wobble "on accelerating / decelerating" "Noisy Inside Car" steering linkage: causes the steering wheel to wobble at 40+ mph decelerating harder to control "Steering wheel wobble "on accelerating / decelerating" My brothers car had the above problems I changed his rear spindle, outer, tie rods, "both were shot" bad bearing "blown bearing"
the fuel filter or carburetor might be plugged, really need to know when it jerks be it accelerating or stopping.
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
The velocity-time graph for a car first accelerating and then decelerating uniformly would have a positive slope during acceleration, representing an increase in velocity, and then a negative slope during deceleration, showing a decrease in velocity. The graph would form a "V" shape with two straight lines meeting at a point where the acceleration changes to deceleration.
The velocity of a car can change by increasing its speed, such as accelerating when pressing the gas pedal, or by decreasing its speed, such as decelerating when applying the brakes.
why is my car jerking
Answer Humming noise from front endI just got my car fixed with the same problem and it was the wheel bearing and it is gone. Was it a fwd car?
The fastest production (as opposed to custom built or modified) car was the Bugatti Veyron (which is still the fastest accelerating & decelerating car in the world), but the current highest speed production car in the world is the SSC Ultimate Aero TT at 257mph.
When a car is travelling at a steady speed, the driving force from the engine is equal to the total resistive forces acting against the car, such as air resistance and friction. This balance of forces allows the car to maintain a constant velocity without accelerating or decelerating.
