Distance vs Displacement | Physics in Motion

The video tutorial explains the concepts of distance and displacement, highlighting their differences. Distance is the total path traveled, while displacement is the change in position from the starting point, including direction. Examples include a car trip, a soccer player's run, Amy's run, and Jermaine's track laps. The importance of direction in displacement is emphasized, using cardinal directions for clarity.

What is the main difference between distance and displacement?

• Distance includes direction, displacement does not.

• Distance is the total path traveled, displacement is the change in position.

• Distance is measured in time, displacement in length.

• Displacement is always greater than distance.

If a car travels 10 miles to a store and then returns home, what is its displacement?

• 20 miles

• 10 miles

• 5 miles

• 0 miles

In the car travel example, why is it important to specify a direction for displacement?

• Because direction affects the total distance.

• Because distance and displacement are the same.

• Because displacement is a vector quantity.

• Because displacement is a scalar quantity.

A soccer player runs 40 meters north and then 15 meters south. What is the player's displacement?

• 25 meters north

• 25 meters south

• 55 meters north

• 55 meters south

Why is the direction north used in the soccer player example?

• Because the player runs faster north.

• Because the player starts facing north.

• Because the player ends south of the start point.

• Because the player ends north of the start point.

Amy runs 2 miles south and then 3 miles north. What is her total distance traveled?

• 2 miles

• 3 miles

• 5 miles

• 1 mile

Jermaine runs 2 laps around a 400-meter track. What is his displacement?

• 0 meters

• 200 meters

• 400 meters

• 800 meters
