Question

In virtue lab, we have a car and a fan; fan use to create wind; if the car run along the wind direction, it will move faster and faster; but if the car run against wind direction, it will slower and at some point, the wind the force push the car back to it start point. Explain how the principle behind the lab can be used to model something in the real world. Describe any simplifying assumptions and why it is a good model or bad model. If it is a bad model, discuss any changes you would make to make it a better model. 

Explanation / Answer

The principle behind is the force of moving gas affect onobject. The force of gas or air affect of object is depended on therelative velociy of the gas to the object. ----- in simplifying, the force that the gas excert on the car can beassumed to be unchanged if the wind speed is pretty big to thespeed of the car( so the relative speed didnt change much when thecar's speed changed). --------------- to make it a better model we should make sure that the speed of thecar in the whole time do not become so big, to make this we canincresease mass of the car, increase speed of wind but not theamount of gas flow toward the car. (reduce the density).
