الكميات الفيزيائية القياسية والمتجهة: الفرق بين المسافة والإزاحة

The video tutorial explains the difference between distance and displacement using an example. A person travels 30 meters north, 60 meters east, and 30 meters south, covering a total distance of 120 meters in 60 seconds. The displacement is 60 meters east, and the average velocity is 1 meter per second eastward.

What is the initial direction and distance covered by the person in the example?

• 60 meters west

• 60 meters east

• 30 meters south

• 30 meters north

How much total distance does the person cover in the example?

• 100 meters

• 90 meters

• 150 meters

• 120 meters

What is the total time taken by the person to cover the entire distance?

• 70 seconds

• 80 seconds

• 50 seconds

• 60 seconds

What is the displacement of the person from the starting point to the endpoint?

• 30 meters south

• 60 meters east

• 30 meters north

• 60 meters west

How is the average velocity of the person calculated in the example?

• Displacement divided by total time

• Total distance divided by displacement

• Displacement divided by total distance

• Total distance divided by total time
