It's a basic fact for every being: When you work hard, you feel like you've lost energy. In this story, for example, Anita pulls a rubber band tightly and the energy she produces propels the rubber band across the room. We discovered where our energy goes and why it goes there in Unit V: Conservation Laws. To begin, there is one fact about energy that is critical to understanding the rest of the unit: Energy may be transferred in a multitude of ways, but the total amount of transferred energy is unchanged. In other words, the energy is conserved - hence the title of the unit, "Conservation Laws." There are three methods of energy transfer: Working, heating, and electromagnetic radiation. This rubber band situation focuses on the transformation of energy through working.
Good Blog Posting, Paige. I liked how you did a problem that got the wrong solution rather than the normal old problem that comes out with an easy answer. You might want to copy and paste your first paragraph into a word document to check for some typos. But all in all, great posting!

Your posting is creative and the comic strip is well done.
ReplyDeleteA few comments:
In the first line you said: "It's a basic fact for every being: When you work hard, you lose energy." but then you claim that "the total amount of transferred energy is unchanged. In other words, the energy is conserved" Please explain which one is true: is energy lost or transformed?
The last paragraph indicates that the "rubber band situation focuses on the transformation of energy through working." but there is no indication of work in the comic strip or in the equations. Please make the necessary changes.
I like the idea of the problem but it is not clear where the data comes from. You said the distance is 5 m "therefore" the velocity is 5 m/s, why is that? where is the number coming from? Please justify.
On the problem you said that the '1/2' cancels out but then you use it to multiply by a number.
Also you probably meant square root not 'route'.
Looking forward to reading all the improvements!
can you please make funnier comic strips about science
