text: # Motion in 1 dimension- Part 1
  
  Learning Objective: Understand motion, velocity and speed
  
  Vocabulary:
  displacement
  velocity
  average velocity
  speed
  scalars and vectors
  
  How is velocity measured?
  
  Now calculate Big Daddy Don Garlitz’ average velocity by converting 0.25miles/5.40sec into miles per hour.
  
  (0.25miles)/(5.40sec) x (3600sec/hr) = 166 mph
  Why is this different than the 270 mph recorded top speed?
