Monday, November 3
Read in your text pages 146-152 on projectile motion. In your lab notebook title the assignment Projectile motion and define a) Projectile Motion b) Trajectory c) Range Then: 1.Explain how the trajectory of an object depends upon the frame of reference from which it is observed 2. Draw a force diagram of a projectile at the apex of its trajectory. 3. Two baseballs are pitched horizontally from the same height, but with different speeds. The faster ball crosses home plate within the srike zone, but the slower ball is below the batter's knees. Why does the faster ball not fall as far as the slower one? 4. Suppose that an object is thrown with the same initial velocity and direction on Earth and on the Moon, where g is one-sixth that on Earth. How will the following quantities change? a) Vx b) the object's time of flight c) ymax d) R
Tuesday, November 4p.
Moon lab due is due tomorrow. Bring text book as text will be used in class on Wednesday.
Friday, November 7
Final exam on Monday. Reveiw notes and text, particularly pages 96-107 (2nd and 3rd Law); p.146-152 projectile motion. You can also visit www.physicsclassroom.com and navigate through the chapters for practice problems on Newton's laws and projectile motion. Remember to bring a quart size juice/milk container for Wednesday's project.
