Homework: Unit Conversion & Dimensional Analysis- 2 and 3
On Friday in class we went over scientific notation and sig figs while listening to the theme music above. We then moved onto unit conversions. We went over how to convert one unit to another and did Unit Conversin % Dimensional Analysis 1 in class.
One example we did in class of unit conversions;
We want to see if the song seasons of love was true, and there were 525,600 minutes in a year, so the equation for this would be
525,600 min X 1hour/60min X 1 day/24hour X 1 year/365 days
It's hard to show on this blog but basically, you want to clear the unit on top by including it in the denominator of the thing your multiplying by
Another example we did was;
Finding out how fast Jamie walked in miles per hour, but since we calculated it in meters per second, we had to do some converting
So the work for this would be;
11meters/11.05sec X 3.28 feet/1 meter X 1mile/5280feet X 60second/1 min X 60min/1hour
This would equal 2.2 mph.
Sorry again for the equations, but it's the best I could do. Go see Mr. Paek if you need more help. But I hoped you like the blog theme music!
