Unit 2 - Is that moving?

Relative to what?

In Unit 2, we learned about how everything is always in motion, but it depends on what it's relative to. For instance, a outer part of a fan is not in motion in relation to the ground, but it is moving in relation to space. The blades of a fan, when it's turned on, are moving both in relation to the ground and in relation to space. (try and tilt your head. I have no idea how to rotate pictures on this).
We also learned about vectors, which I had learned a little bit about previously in the last cycle or two of Geometry. And I always, without fail, say it in Jason Segal's voice from Despicable Me. Something new that we discussed in class was scalar quantities, which is a quantity that has magnitude, or muchness. Vector quantities are similar, but along with magnitude they also have direction. Scalar quantities are things like distance or speed, and an example of a vector quantity is displacement, or the distance between where you are now and where you started.

  1. Maya, you're post was filled with everything we learned and you also made it interesting and funny. I like how you put Despicable Me in it. I also like your picture, I never would of thought about it, but it's a really good idea! Wonderful job!

  2. If I burst into laughter the next text, its because I'm just imagining "size and magnitude!" Your post made the physics of ordinary objects really interesting and humorous.
