 * Today, class started with two daily questions. Mr. Manning had students copy these questions down in their notes, along with their answers.

1. Why does the vertical component of velocity for a projectile change with time, whereas the horizontal component doesn't? The answer to this is that the vertical component of velocity has the gravity component acting on it, which will effect the acceleration, and the horizontal does not have gravity acting on it. 2. True or false: When air resistance does not affect the motion of a projectile, it's horizontal and vertical components of velocity remain constant.**
 * FALSE

Mr. Manning then had students take out page 6. Page six deals with projectile trajectory motion. The students had to calculate the horizontal and vertical motion. (Number 3) After calculating the two components, students then had to graph the trop the projectile took on page seven. Class then ended with the students working on different scenarios using projectile trajectory motion, using equations from the kinematics unit. REMINDER!!!!!! AMUSEMENT PARK PHYSICS IS DUE ON MONDAY!**
