In unit 2 we learned about motion, specifically distance, velocity, speed, acceleration, and time. A car is a great example of each of these factors in physics. A car demonstrates acceleration when it starts, stops, and changes speed. This is an essential part of a car because if you couldn't start, stop, or change the speed of a car, it would either not work or be very dangerous. As we covered in class, speed is measured by a speedometer. A car is capable of traveling great distances in a short amount of time, and at a relatively high rate of speed. This is an important way that physics makes life easier. A car on a freeway is a great example of velocity. On the freeway, you can't turn around. You are kept to going in a relatively same direction. On a regular road it is more difficult to track velocity, due to turns and potential complete change of direction. Overall, the uses for a car are a great example for what we learned in unit 2.
This is a really good example because a car can represent several of the new ideas we learned. It's easy to visualize and understand the concepts in a simple and relative way because we are all familiar with cars. We're comfortable with cars but not so much with physics.
ReplyDeleteI agree with your example. In fact, I also used a "motorized vehicle" example for my blog as well (check it out!).
ReplyDeleteHowever, I do have a question about your post. You said that on a freeway, you can't turn. Is this true?
Do you mean to tell me that a freeway goes exactly straight? How would you get on and off it if this was the case? It doesn't curve at all?
by using the example of a freeway, I meant that you really can't flip around and drive in the opposite direction. There are no stoplights and the speed (other than when there is traffic) is mostly consistant.
ReplyDeletegreat example kim also did it but with a plane
