Distance versus Displacement
  • A ferry boat captain and a truck driver are
    asked how far it is from Vectorville to Component
    Cove .

3
The truck driver's response
  • 80 km.

4
The ferry boat captain's response
  • 50 km.

5
Who's right?
  • There is a discrepancy in the accuracy of how
    far it is from Vectorville to Component Cove.
  • The ferry captain actually has the correct
    answer. When deciding how far it is from one
    place to the next, we need to measure directly
    from point A to point B.

6
Distance versus Displacement
  • The distance between two points is the total
    "ground" that is covered. This would be how far
    the truck driver traveled.
  • Displacement is how far it is from point A to
    point B. This would be how far the ferry boat
    traveled.

7
Scalar Quantities
  • A scalar quantity has magnitude.
  • Distance is a scalar quantity.

8
Vector Quantities
  • A vector quantity has magnitude and
  • direction.
  • Displacement is a vector quantity.
