1D Motion 2/3

What is the difference between distance and displacement?

• Distance is from point A to point B.
• Displacement is the shortest distance along 2 points and direction matters.
• Displacement is distance and direction matters.
• There is no difference.

How do we measure velocity?

• stopwatch
• distance/time
• time/distance
• displacement/time

What are the units speed is measured in?

• m/s²
• m
• hr
• m/s

The distance-time graph for an object with a positive velocity would be a line with ____

• no slope
• positive slope
• changing slope
• a curve

The position-time graph for an object with a velocity of zero would be a line with ____.
