2.2 - Where and When
  • ENGAGEMENT
  • Objectives:
  • Students will define a coordinate system for the motion of an object, recognize that the coordinate system affects the sign of an object's position, define displacement, and determine time interval in order to use a motion diagram to answer questions about an object's position, displacement, and time interval.

  • WARM-UP
  • 1. What are the four kinds of motion?
  • 2. Draw a motion diagram for a car speeding up.
  • 3. When should a particle model be used for a moving object?
