Lesson 2.4.3

Lesson 3 — Average Velocity

Get Focused

Average velocity requires a consideration of the direction of motion. As the calculation of velocity requires the use of displacement the direction of travel, relative to a specific reference point is needed. In this lesson we will investigate the calculation of velocity with reference to direction.

Consider the following essential questions as you complete Lesson 3:

  • Why is displacement important for the calculation of velocity ?
  • How is velocity different from speed ?
  • How does direction factor into the calculation of velocity
