073B: Last Saturday was December 7th. That day in 1941 was significant in the history of the United States. If you're interested in learning about how politics affects nature, and how the fourth largest lake in the world disappeared in less than a century, here's a great video: https://www.youtube.com/watch?v=AZ5kVH5Ijfg

And, if you'd like to learn about who fired the first shot in Pearl Harbor (it wasn't the Japanese), click below. There's couple REALLY interesting twists to the story, both of which get revealed at the end.

#Goals:

SWBAT...

1. ...correctly answer 80% of the review questions

Warm-Up

Consider the trajectory diagram shown below for a projectile thrown at an angle to the horizontal. The vector arrows represent the horizontal and vertical components of the projectile's velocity. Several points in the trajectory are labeled with a letter. Use the trajectory diagram to answer the next several questions. (Consider air resistance to be negligible.)

32. At which point(s), if any, are there no forces acting upon the object? List all that apply.

33. At which point(s), if any, are the forces acting upon the object balanced? List all that apply.

34. At which point(s), if any, is there a net force acting upon the object? List all that apply.

35. At which point(s), if any, is the net force acting upon the object directed toward the right? List all that apply.

36. At which point(s), if any, is the net force acting upon the object directed upward? List all that apply.
