This is a video of a BMW speeding up as fast as it can showing its high acceleration rate. The car goes from stopped to a very high speed in just a few seconds. When the car is going straight it has a constant velocity. When the car is turning, however, it only has a constant acceleration because you can not have constant velocity without the object going in only one direction.
1. I like the fact that it is as if you are riding in the car. The personal feeling is nice because you hear the noise of the car accelerating making the acceleration more easily identified.
ReplyDelete2/3. My blog was also about a car, but instead of a BMW on a regular road it was a race car on a race track. Another difference is that mine comparted constant velocity and constant speed while yours compared constant acceleration and constant velocity.
4. I think that something that would make your blog even better is to go more in depth of the difference between constant acceleration and constant velocity. A clear definition of both closer to the beginning would make the argument more clear and easier to understand your example.
