U have a Vaccum leak @ your resivoir for all your ac & heating controls.Sometimes a cracked Vaccume line from the Engine Intake Manifold 2 the AC Canister will do the same.Some cars have a container that looks like a fruit juice can mounted under the hood Ford/Chevy/Dodge etc ALL will do the samething because of a VACCUME leak.

Causes of a refrigerator to stop cooling and ice forming on back of frost free freezer?

seriously nothing being said about automatic defrost and defrost timer ...could be that its not going through its defrost cycle meaning its stuck on cooling cycle and creating your frost in freezer means bad defrost timer,not going into defrost mode ..old units have manual timers new refrigeraters have computer boards.try unplugging refrigerater for 24hrs open door and let defrost, then plug in, if you get refrigerator to cool that next day ...more then likely its the defroster timer

Acceleration is related directly to motion. When you accelerate you are going into motion. So motion is directly related to acceleration. :D

Dodge Ram hesitates during acceleration?

For a 2009 Ram, Yes.Try experimenting with the AC/Heat Controls. I have noticed when defrost is on there is a miss in the acceleration, but when the floor heat is on, the acceleration is okay. I am taking mine in to see what they say about this. My 2000 Dakota had a miss in the acceleration but the dealerships could never find the problem (or did not care).1973 Dodge Coronet (318 Auto); 1993 Dodge Dakota Sport (3.9 Standard); 2000 Dodge Dakota Sport (3.9 Standard); 2009 Dodge Ram (4.9 Auto)...Things have been going downhill ever since I brought the 2000 model, and am not happy with the 2009. Needless to say, this is my last Dodge.

How can recognize acceleration?

Acceleration is a change in speed or velocity. So if you going faster than your starting speed your accelerating. If your changing direction (a change in velocity) then that is also acceleration.

What is acceleration of a Car that is going at a steady speed of 50 mph?

Zero. Acceleration = change in velocity/change in time As you see the conditions are not met for acceleration to be taking place.

How is acceleration represented in a speedometer?

Acceleration is not represented on a speedometer, however, when you look at the speedo, if the needle is moving, you can get a rough idea of acceleration like this: If the needle is going clockwise (of generally indicating faster speeds) - you are accelerating. If the needle is going anticlockwise - you are decelerating. Speedometers measure speed. You would need an accelerometer to measure acceleration.

When acceleration and velocity are pointing in opposite direction?

Restate the question: When are acceleration and velocity pointing in the opposite direction? If you are going forward but slowing down, then the velocity is positive, but the acceleration is negative.

Which is greater an acceleration from 25kmh to 30kmh or an acceleration from 96kmh to 100kmh if both occur at the same time?

The acceleration from 25kmh to 30kmh is greater. Acceleration is the rate change in velocity with respect to time (dv/dt). Going from an initial velocity at one point in time to a final velocity at a later point in time, the average acceleration is given by (vf - vi)/(tf -ti), the change in velocity divided by the duration of acceleration. Since going from 25kmh to 30kmh is a change in velocity of 5kmh and going from 96kmh to 100kmh is a change in velocity of 4kmh, and the duration of each is the same, 25 to 30 is the greater acceleration.
