  1. 1What is perceptible motion?Movement this is able to be seen or perceived, especially by the scenes.
  2. 2What is imperceptible motion?Movement that is unable to be seen or perceived, especially by the scenes.
  3. 3What is a frame of reference?A set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.
  4. 4What do perceptible and imperceptible motion depend on?Ex. content, tools, technology or frame of reference
  5. 5What does a vector quantity have?magnitude and direction
    ex. displacement, position, velocity
  6. 6What does a scalar quantity have?magnitude
    ex. distance, time, speed, direction
  7. 7What is the difference between vector and scalar quantities?Vector quantities has magnitude and direction while scalar quantities only has magnitude.
  8. 8What does the symbol "i" stand for?Initial
  9. 9What does the symbol "f" stand for?Final
  10. 10What does the symbol "vave" stand for?Average
  11. 11What does the symbol "vinst" stand for?Instantaneous
  12. 12What does the symbol Δ stand for?Change
  13. 13What does the symbol "+ve" stand for?Positive motion, up or right
  14. 14What does the symbol "-ve" stand for?Negative motion, down or left
  15. 15What are the symbols for distance?d, dⅈ, df, Δd
  16. 16What unit is used for distance?Meters (m)
  17. 17What is distance?The total length of a journey including twists, turns and changes in direction.
  18. 18Is direction a scalar or vector quantity?Scalar
  19. 19What are the symbols for displacement?Δd ⃗ ,df ⃗ , di ⃗
  20. 20What unit is used for displacement?Meters (m)
  21. 21What is the equation for calculating displacement?Δd ⃗ =df ⃗ - di ⃗
  22. 22What is displacement?How much the position of an object changes, if you start and finish at the same place then Δd ⃗ = 0.
  23. 23Is displacement a vector or scalar quantity?Vector
  24. 24What are the symbols for position?d ⃗, di ⃗, df ⃗
  25. 25What unit is used for position?Meters (m)
  26. 26What is position?The description of an objects location, as seen by an observer from a particular viewpoint.
  27. 27What does position always require?A reference point
  28. 28Is position a vector or scalar quantity?Vector
  29. 29What are the symbols for time?t, ti, tf, Δt
  30. 30What unit is used for time?Seconds (s)
  31. 31What is time?Description of when an event occurs (initial time is often "0") time intervals describe the duration of the event.
  32. 32Is time a vector or scalar quantity?Scalar
  33. 33What is the time interval calculation?ΔT = Tf - Tⅈ
  34. 34What is the symbol for speed?V
  35. 35What unit is used for speed?Meters per second (m/s)
  36. 36What is speed?Description of how fast something is moving.
  37. 37Is speed a vector or scalar quantity?Scalar
  38. 38What are the symbols for velocity?v ⃗, vi ⃗, vf ⃗, vawe ⃗, vinst ⃗, Δv
  39. 39What unit is used for velocity?Meters per second (m/s)
  40. 40What is velocity?Description of how fast an object's position is changing.
  41. 41Is velocity a vector or scalar quantity?Vector
  42. 42What are the symbols for direction?+ve, -ve
  43. 43Is direction a vector or scalar quantity?Scalar
  44. 44What are two reasons to graph data?-easy to see and understand
    -easy to compare different data
  45. 45What is a variable?Observable quantity
  46. 46What is an independent variable?Variable that we change or control
  47. 47What is a dependent variable?Variable we observe or measure
  48. 48On a graph is the dependent variable on the "x" or "y" axis?y- axis
  49. 49On a graph is the independent variable on the "x" or "y" axis?x- axis
  50. 50What are the five parts of a graph?1. x- axis= title and unit
    2. y- axis= title and unit
    3. graph title= subject specific and descriptive
    4. scale= should extend past the last data point
    5. best fit/ trend line
  51. 51What is the scale on a graph?The distance between values on an axis.
  52. 52What are the two steps to calculating slope?1. Pick two points on the best fit line that is not a data point.
    2. Enter point values into slope equation then solve
  53. 53What is the equation used to calculate slope?= y2 - y1 / x2 - x1 = rise / run
