What is a good example of a positive feedback mechanism?

I was thinking about this one example:

We are trying to figure out which direction our car will move.

But sometimes, our car is not moving at all and we don't know why (it's not moving at all?). Well if it doesn't move then it's no good telling us what direction to move so we end up stopping the car and trying again. And the car will not be stopped again. It just goes around and around in circles until a driver stops it because it's driving him crazy.

In this case we have a positive feedback mechanism as soon as our car doesn't move it creates a self reinforcing loop because we didn't know how to tell it how to move and now we know how to tell it how to move. So is it clear what type of positive feedback I am talking about? If you were to think about examples that you know you can't give a direction to they would need to involve a self reinforcing loop where the system is always doing more of itself because of the feedback. Am I correct so far? You seem to be thinking too much about what is feedback when it's really a simple loop: positive feedback becomes negative feedback. What you're describing is just a positive feedback loop: if your car doesn't move, move in the other direction.

For example: a thermostat for the oven turns on, it's temperature high temperature; a person turns on the oven, it's temperature low temperature; the person sees the high temperature and turns thermostat back to it's position "normal temperature". Now after that action there is a feedback loop because it was the oven heating. This has been called a positive feedback loop. We can also have a negative feedback loop. This would be the oven with a cold temperature, turning on thermostat which has turned off the heat and then the person leaving the oven. We then have a negative feedback loop because the oven was cooling but thermostat was off. The oven could then turn back on and go back to its normal state, or else the person would be cooling the oven without thermostat and that would be bad.

What are the five examples of negative feedback mechanism?

The best way to learn a complex skill, such as playing a musical instrument, is by observing an expert at work.

This process is called learning by doing. Observing an expert: Watching a musician while performing will help you learn how to play the instrument. This is also true for learning how to do other things.

Following an expert: You can mimic someone's actions and observe how they get there. You can watch how someone does something, then decide how you would like to accomplish the same thing.

Using a tool: A tool can be used to get a desired result. For example, if you want to write a book, you can use a pen and paper or a laptop. If you use a pen and paper, you must write out every single idea that comes to your mind. If you use a laptop, you can use its word processor or spreadsheet program to capture your ideas.

Doing it yourself: You can try doing the task on your own. Then, when you get stuck, you can observe how someone else did the same task.

Receiving feedback: You can ask someone else to give you feedback about your performance. If you are unsure of whether you are doing well or poorly, ask someone who knows about the task to point out the good and the bad.

Negative feedback (NFB) is any signal that indicates that the system is not operating as it should. When the system receives NFB, it must either respond by adjusting its behavior, or ignore the signal, or else the system will break down. In other words, when NFB occurs, the system must adjust itself or else shut down.

What is negative feedback? Positive feedback is a signal from a sensor that tells the system what it needs to know to keep the system stable. Negative feedback, on the other hand, is a signal from a sensor that tells the system what it needs to know to change itself in order to stay stable. Negative feedback can be a good or bad thing, depending on how the system interprets the information. If you have a thermostat that detects the temperature and displays it to you on a display, you probably won't bother turning on the heat until the temperature reaches a certain level.
