  2. What is a physical quantity that has both direction and magnitude?

  3. A vector

  4. What is a quantity that can be completely specified by its magnitude but with no direction?

  5. A scalar

  6. What is the answer found by adding two vectors?

  7. The Resultant

  8. What is the result of multiplying or dividing vectors?

  9. Vectors

  10. A car moves north 30 miles then puts it in reverse for 15 miles. What is its displacement from start to finish?

  11. 15 miles North

  12. What is and object that is launched or thrown into the air that is subject to gravity?

  13. A projectile

  14. What is the path of a projectile?

  15. A parabola

  16. What slows down a projectile while in flight?

  17. Air resistance

  18. Once a projectile is fired horizontally, neglecting resistance, what is its acceleration?

  19. 0 m/s²

  20. The royal Gorge Bridge in Colorado rises 320m above the Arkansas river. Suppose you kick a little rock horizontally off the bridge. The rock hits the water such that the magnitude of its horizontal displacement is 50m. Find the speed at which the rock was kicked.

  21. 6.2 m/s

  22. What do velocity measurements depend on?

  23. The frame of reference of the observer

  24. When a projectile is fired at and angle, what will its velocity be when it hits the ground?

  25. The same as its initial velocity, but negative

  26. What is the range of a projectile?

  27. The horizontal distance it covers

  28. What is the amount of time a projectile is in flight called?

  29. Hang time

  30. A boat heading north crosses a wide river with a velocity of 20 km/h relative to the water. The river has a uniform velocity of 10 km/h due east. Determine the boat’s velocity with respect to an observer on shore.

  31. 22.36 km/h @ 46 degrees east

  32. What is the Pythagorean theorem?

  33. A² + B² = C²

  34. What is the Sin equation?

  35. Opposite side over hypotenuse

  36. What is the Cos equation?

  37. Adjacent side over hypotenuse

  38. What is the Tan equation?

  39. Opposite side over adjacent

  40. A man moves 80 m horizontally, then travels 40 m at an angle of 30 degrees above the horizontal. What is its displacement from the starting point?

  41. 116.37 m

  42. What angle gives the greatest hang time?

  43. 90 degrees

  44. What angle gives the greatest range?

  45. 45 degrees

  46. What angle gives the greatest height?

  47. 90 degrees

  48. How would an increase in mass effect the range of a projectile?

  49. It wouldn’t

  50. How would an increase in velocity effect the range?
