10/6 Finney

     We turned in the linear regression practice and the golf ball lab where you measure the height of the visitor's side bleachers. Then without wasting time, we jumped into lab pages 41-44 which, if you didnt finish, became homework along with the 1st Quarter Honors Physics Review Problems worksheet.

Qod- What are the patterns in free fall that you discovered today?
     While doing the lab on pages 41-44 we discovered that, if you throw an object straight into the air, the point where it's height is the greatest, is also the point where it's velocity is the lowest. Heading to that point, which happend to be at 4 seconds in the lab, the velocity decreased in a constant rate. So, the initial velocity was 39.2m/s, and every .5 seconds it decreased 4.9m/s until it reached 0m/s at 4 seconds. Then, when the object started heading towards the ground it began increasing it's velocity in the negative direction(down).
