  1. Physics Team Trivia! Quarterly Exam I Mr. Richter

  2. First Quarter Categories • Precision and Accuracy • Upward Launches • Metric Prefixes • Acceleration

  3. Precision and Accuracy • Student A measures a distance to be 4.3 meters and Student B measures the same distance to be 4.32 meters. Student A is: • Less precise • Less accurate • Both less precise and less accurate. • Neither less precise nor less accurate.

  4. Precision and Accuracy • A. Student A is equally as accurate but less precise, measuring only to the nearest tenth of a meter.

  5. Upward Launches • An object is launched upward at +5m/s. What is its acceleration at the peak of its flight?

  6. Upward Launches • -9.81 m/s2

  7. Metric Prefixes • What metric unit is 100,000 larger than a centimeter?

  8. Metric Prefixes • A kilometer

  9. Acceleration • What is the acceleration of an object traveling at a constant 4 m/s for 3 seconds?

  10. Acceleration • 0 m/s

  11. Picture Round

  12. Second Quarter Categories • Significant Figures • Acceleration • Free Fall • Variables

  13. Significant Figures • The dimensions of a room are 14.3 m by 6.2 meters. What is the area of the room with significant figures?

  14. Significant Figures • 87 m2. Two significant figures.

  15. Acceleration • What is the acceleration of an object traveling to the right whose speed is decreasing by 5 km/h every second?

  16. Acceleration • -5 km/h/s

  17. Free Fall • Assuming no air resistance, which, if either, will fall faster: a brick or a feather?

  18. Free Fall • Neither. In a vacuum, all objects fall at the same rate.

  19. Variables • A student decides to see if there is a relationship between how loud his music is and how fast he drives as a result. Name the independent and dependent variables.

  20. Variables • Independent: how loud the music is • Dependent: how fast he drives

  21. Half Time! Review the rules.

  22. Calculate • A potted plant falls from a balcony and takes 1.20 seconds to hit the ground. How high is the balcony.

  23. Half Time: Calculate • 7.06 m high

  24. Third Quarter Categories (2, 4, 6 or 8 points) • Metric Prefixes • Upward Launches • Average Velocity • PvT Graphs

  25. Metric Prefixes • How many millimeters are in 32 meters?

  26. Metric Prefixes • 32,000 millimeters

  27. Upward Launches • A golf ball is struck from the ground and takes 2.2 seconds to reach its maximum height. What is the total time it is in the air before it returns to the ground?

  28. Upward Launches • 4.4 seconds

  29. Average Velocity • A wide receiver runs 35 meters down field and then 10 meters back up field in 7 seconds. What is his average velocity?

  30. Average Velocity • 3.6 m/s downfield

  31. PvT Graphs • Sketch the PvT graph of an object starting from rest at the origin, and experiencing constant negative acceleration.

  32. PvT Graphs

  33. Third Quarter Bonus

  34. Third Quarter Bonus: Vocab • Write the terms that are defined by the following definitions: • how close a measurement is to the true value • how exact a measurement is • a variable that is kept the same in an experiment • a volume 1,000,000 times smaller than one liter (L) • a coordinate systems for specifying the location of objects in space

  35. Third Quarter Bonus: Vocab • Accuracy • Precision • Control Variable • Microliter (μL) • Frame of Reference

  36. Fourth Quarter Categories • Scientific Notation • The Scientific Method • Acceleration Calculation • VvTGraphs

  37. Scientific Notation • Write the following two measurements in scientific notation. • 432 • 0.0037

  38. Scientific Notation • 4.32 x 102 • 3.7 x10-3

  39. The Scientific Method • All scientific experimentation comes from one first step. What is it?

  40. The Scientific Method • A question!

  41. Acceleration Calculation • A cyclist pedaling at 3.5 m/s accelerates at a rate of 1.2 m/s2 for 4.5 seconds. What velocity does the cyclist reach?

  42. Acceleration Calculation • 8.9 m/s

  43. VvTGraphs • Sketch the Velocity vs. Time Graph of an object moving backward with zero acceleration.

  44. VvTGraphs

  45. Final Round

  46. Calculation • A race car driver brakes to a stop from 32.0 m/s in 6.00 seconds. • What is his acceleration? • How far does he travel while he is stopping?

  47. Final Round • -5.33 m/s2 • 96.0 m
