##### ### Henderson's Regular Physics Quizzes (1998-99 School Year)   ### Suggestions for this week's quiz (Unit 3, Quiz#2): This week's quiz on Unit 3 material is tentatively scheduled for Friday, October 30. The quiz will be a one-page quiz, covering both sides of a single sheet of paper. The equations for average velocity and the sine, cosine, and tangent functions will be provided. Other than a calculator, no other helps will be provided nor allowed. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz: To know the definition of a projectile and some basic principles characterizing the motion of a projectile (free-body diagram, independence of vx and vy components, variation of vx and vy with time, values of ax and ay, etc.). To apply one's understanding of projectiles in order to analyze numerical information in the form of trajectory diagrams (such as p. 24, #3 and p. 25, #6) and velocity-acceleration-time tables (such as p. 25, #7). To use concepts of projectile motion and the kinematic equations in order to solve problems involving the horizontal launching of projectiles from an elevated position; typical unknowns include the time of flight, the horizontal range, the initial height and the initial launch velocity. To be able to use SOH CAH TOA in order to resolve a velocity vector into horizontal and vertical components. To use concepts of projectile motion and the kinematic equations in order to solve problems involving the launching of projectiles at angles to the horizontal; typical unknowns include the time of flight, the horizontal range and the peak height (see Supplemental Challenges and p. 26, #8 and #9). To use projectile principles to explain various real-world phenomena such as those discussed in demonstrations and laser disc segments - the snowmobile and the flare and the airplane and the flare. An understanding of previous concepts from the first two units. Use the links below to see the Studying Suggestions for the two Unit 1 quizzes, the two Unit 2 quizzes, and the previous Unit 3 quiz.
