Multiple Choice Directions: Choose the letter of the best answer. Write your answer on a separate sheet of paper. What is trajectory? A. the highest peak of a projectile B. the time of flight of a projectile C. the parabolic path followed by a projectile D. the horizontal displacement of a projectile Prim 2. It is the height from a projectile's path when the vertical component equals zero. A. minimum height B. maximum height C. range D. trajectory 3. In a projectile, the displacement in the horizontal direction is called A. minimum height B. maximum height C. range D. trajectory 4. The launch angle of a projectile can be anywhere from A. 0 to 45 degrees B. 0 to 90 degrees C. 0 to 180 degrees D. 0 to 360 degrees 5. In projectile motion, as you make the launch angle greater, the maximum height will A. be higher B. be lower C. remain the same D. become zero 6. What happens to the range of a projectile if you keep increasing its launch angle? A. It will increase until 45° then decrease from there B. It will decrease until 45° then increase from there C. It will increase until 45° then remain the same from there D. It will increase until 45° then becomes zero all throughout 7. Given the same initial velocity, 45° is the launch angle that will result to the A. shortest range. B. longest C. fastest D. slowest 8.

Part A: Knowledge and Understanding Questions Answer the following multiple choice questions by choosing the most appropriate answer. Place your answer in the answer key on the first page of your test booklet. 1. Which one of the following is NOT consistent with a car which is accelerating? a. moving with an increasing speed. b. moving with a decreasing speed. d. changing direction. c. moving with a high speed. 2. Anna Mungal is running down the football field in a straight line. She starts at the O-yard line at 0 seconds. At 1 second, she is on the 10-yard line; at 2 seconds, she is on the 20-yard line; at 3 seconds, she is on the 30-yard line; and at 4 seconds, she is on the 40-yard line. This is evidence that, a. she is accelerating b. she is covering a greater distance in each consecutive second. c. she is moving with a constant speed (on average). d. none of the answers are correct 3. Which one of the following quantities is NOT a vector? a. 10 mi/hr, east b. 10 mi/hr/sec, west c.…
