In the latest of unit 2 that we have learned, we learned about the different line shapes and how based on the slopes of these lines you know what their velocity is. If a line is facing downward on a position vs time graph you know that the the slope is negative and that the object is moving away from its starting point. We also learned about how to draw velocity vs time graphs and how a vertical line is impossible to make in our world.
This picture is a real life graph, if you observe closely and imagine. My stick (the wooden one) is a line on a position vs time graph you can see that it has a negative slope. This means that the line is going downwards as time progresses.
This picture is a velocity vs time graph, if you can again imagine it. Look at the white stick it is perfectly vertical. In class today we learned that a vertical line is impossible to achieve because you're moving and not moving at the same time. Thus it can't ever be achieved in the outside/real/our world, it can be drawn and talked about but to physically make a graph with a line like this is impossible. Trippy isn't it? This is Jacob Sparks in the photo with the white stick.

Gio, you had some interesting, but good examples. The last example was a little confusing though.
ReplyDeleteMy bad, the last one was sort of hmm, Jacobs stick is vertical. A vertical line can never exist in the real world because you're moving and not moving at the same time. It's kind of hard to explain and i also don't think I'm explaining it that well either. If you want you could maybe ask Mr Blake about it! :)
ReplyDeleteGood job gio. Very descriptive and in depth with the kinematics topic. I like your examples with lacross, they were very unique and interesting.
ReplyDeleteThis is actually a really good description of what we learned and you represented it well by using your sport. You used a lot of new terms we used and made it easier to understand using real world connections. Very good
ReplyDeleteI like the way that you made a representation of a graph and didn't use a tradition graph. i also liked how you used picture of lacrosse to show speed and velocity. this is a really unique idea and it works great for this situation.
