Bum bum bum bum bum iiiiiiiiiiiiiiiiiiiiiiiiiit's LAB TIME!
There comes a time in every unit when we have to band together, unite as brothers to complete an intense and life endangering mission.
Yeah okay, that may be taking it a bit far, but lab's are a huge part of every unit and, more often than not, they challenge us to be creative thinkers and problem solving individuals. This lab demonstrated the ideas we've learned thus far in regards to this nifty thing called Torque (looking back at my old blog posts I've realized I really like the word nifty).
Using only a meter stick, a 100g weight, and a calculator, we managed to find the mass of a meter stick.
To begin we had to get our facts straight, making a list of formulas:
Torque= lever arm x force
Force= mass x gravity
Then we stated some common facts, y'know, those things you think you know but always forget:
Torque will be the same on both ends of the stick because opposing torques must cancel one another out for an object to remain in balance.
The Center of mass will be in the center of the object.
Now the real fun can start.
Using these formulas we managed to calculate fairly accurately the mass of the meter stick.
The best part of this lab, for me, was having the chance to teach it to other students, it was so awesome to share what I had learned and I felt it really reinforced my knowledge.
Hi Becca, it's Kat. Although most of your post was great, I think it could have been greatly enhanced if you had included your calculations. As always, it's very well-written and your enthusiasm jumps right off the page. Well done.
