Physical Quantities scalars and vectors: Distance and displacement

The video tutorial explains the difference between distance and displacement using a practical example. A person moves in a path covering 30 meters north, 60 meters east, and 30 meters south, totaling 120 meters in 60 seconds. The displacement is the direct line from start to end, measuring 60 meters east. The average velocity is calculated as 1 meter per second eastward.

What is the total distance covered by the person in the described path?

• 150 meters

• 90 meters

• 180 meters

• 120 meters

How much time did the person take to cover the entire distance?

• 30 seconds

• 60 seconds

• 50 seconds

• 90 seconds

What is the displacement from the start point to the endpoint?

• 120 meters westward

• 30 meters northward

• 60 meters eastward

• 90 meters southward

In which direction is the displacement of the person?

• Westward

• Eastward

• Southward

• Northward

What is the average velocity of the person?

• 1 m/s eastward

• 2 m/s eastward

• 0.5 m/s eastward

• 1.5 m/s eastward
