11-10

Ahh, what a wonderful day of Physics!

Today, Monday 11/10, we started the class by doing a graded Daily-Question. The question had a problem involving Newton's 2nd Law Applications

An example of one of these problems: What is the magnitude of the missing force below?

30 N <--|__5kg___|---> 10 N

a=-4m/s^2 In order to solve this, two things must be done. The first is to find the Net Force. In order to do this we use this equation (Sigma F) = m x a

5 x -4 = -20 N

Since we found the Net Force, now we have to find the missin force. The equation is below: (Sigma F) = F1+F2+F3 so.. -20N = 10N - 30N +F3

Which equals out to be 0 N

Next we worked on a lab called Mass vs. Weight Lab. On Friday we measured some weights that were put on our lab tables and put those numbers on the board, and we copied them down. Today, we did the Observations/Conclusions questions and made a graph that looked like this:



We didn't hand this lab in today, however Mr. Manning told me that it should be handed in tomorrow.

This ended our wonderful day in Physics class.
