Unit 4

Today in class we learned about projectiles. We did a lab that involved launching a ball and figuring out its velocity based on what we knew which was how far the ball was shot, the height it was shot from and the initial/original velocity. We used the information and plugged it into the formulas that we learned in the previous unit (DAT, VAT, VAD). We also learned a new rule that tells us that the axes are independent. This rule is also called the vegas rule because what happens on the x axis stays on the x axis, and what happens on the y axis stays on the y axis. We also went to the pool today and we took videos of people jumping in the pool and we uploaded the videos to logger pro and made a graph for the video and the movement of the different jumps into the pool.

Here is a picture of one of my classmates doing a backflip into the pool. The blue dots are his hip positions throughout the jump.
