This is a picture of a car. This car displays many of the aspects of motion which we learned in class. At the moment, relative to the ground and the fence, this car is not moving. However, relative to space, the car is actually moving quite quickly. The car is capable of speed, a scalar quantity. However, because it is parked, its instantaneous speed is zero. The car is also capable of velocity, a vector quantity. When it goes somewhere, it has positive average velocity. On the way back, it has negative average velocity and because it parks in the same place everyday, its average velocity is zero. For this same reason, its displacement is also zero.
This is very well explained and the example makes it easier to understand. Good Job!
ReplyDeleteWow! This is a great description of what we learned today. In fact, despite my apparent understanding of this topic, you have made it even more clear. On a separate note, I can tell you're an great driver due to your turning your wheels when parked on a slope. However, I can also see that you parked on the wrong side of the street... tisk tisk..
