Topic 2

2. Distance vs. Displacement

3. Distance vs. Displacement
• On your notebook, elaborate on a
definition for both distance and
displacement.

4. Distance vs. Displacement
• On your notebook, elaborate on a
definition for both distance and
displacement.
• Share your definitions with the person
siting next to you.

5. Distance vs. Displacement
• On your notebook, elaborate on a
definition for both distance and
displacement.
• Share your definitions with the person
siting next to you.
• Create a distance vs. time graph for your
morning commute from home to chapel.
(neatness is not an option, it’s a
requirement)

• What would a distance vs. time graph for Michael
Johnson would look like? Draw one. (this is the
400 m dash - one lap around the track)
