Mr. Manning started class off with 2 daily questions today: 1.) True or False: When air resistance its horizontal and vertical components of velocity remain constant After giving us a few minutes to think about it he started asking what we though. After debating on it for a while we came to the conclusion that the question was poorly worded, making it difficult to say if it was true or false. Then we quickly moved onto the next question. 2.) Why does the vertical component of velocity for a projectile change with times, whereas the horizontal component doesn’t. The class seem to understand this question a lot more than the other one. Mr. Manning asked around and we came to the conclusion that its because no forces are acting on the horizontal component, nothing is pushing it , its just inertia causing it to continue to move. After discussing these questions for half the class time we moved on and went to page 6, Projectile Trajectory Activity worksheet. Since we worked on #’s 1 and 2 on Wednesday we moved onto #3. The class alone had to answer a and b. Then Mr. Manning began to ask us for the numbers that we filled the charts for horizontal and vertical motion. After filling half of them in, it was realized by Mr. Manning that we weren’t really focusing enough, so he gave us a graded question. We ended up having to finish the rest of the worksheet for homework because soon after the graded question the bell rang. REMINDER: BRING IN HERSHEY PARK CHECKS AND FORMS DUE FRIDAY!
