Push and Pull

This week we learned about newtons. What they are used for and why we use them. We used them in an lab where we used weights and springs. We graphed the 5 measurements and wrote and equation for it on a white board. We talked about them all in class. On Friday we had a sub and took an assessment on newtons, springs, and weights.

Week of 10/1/12

This past week, we looked at graphs to determine position vs time and velocity vs time. Position vs time we found that how much time it took an object to get somewhere, would determine its position. In the velocity vs time, the velocity of an object would determine its time. This is important to us to know so we can predict how much time it would takes to get somewhere.
