Understanding Distance and Displacement

What is the primary unit of measurement for distance?

• Meters

• Feet

• Miles

• Kilometers

How is displacement different from distance?

• Displacement is always greater than distance

• Displacement includes direction, while distance does not

• Displacement is measured in kilometers, distance in meters

• Displacement is a scalar quantity, distance is a vector

In the example of the child running back and forth, what is the displacement if the child returns to the starting point?

• Equal to the total distance covered

• Double the distance covered

• Equal to half the distance covered

• Zero

Why do taxis charge based on distance rather than displacement?

• Because displacement can be zero even if distance is covered

• Because distance is always less than displacement

• Because displacement is not a measurable quantity

• Because distance is easier to calculate

If a person travels 20 km north and then 20 km south, what is their displacement?

• 20 km south

• 20 km north

• 0 km

• 40 km
