Distance vs. Displacement, Velocity vs. Time

Distance vs. Displacement, Velocity vs. Time

Poll

How can an object travel a distance of 20 meters and have a displacement of zero?

• This is a false statement.  These are the same quantity

• The object traveled north, east, then  south

• The object returned to it's starting place

Poll

The same object has a speed of 3 m/s but has a velocity of zero. How?

• Velocity is scalar quantity

• Velocity is the change in displacement over time.

• Velocity is the change in distance over time
