Velocity

The video explains that velocity is a vector with both magnitude and direction. It provides an example of a plane traveling at 900 km/h northwest. Average velocity is calculated by dividing displacement by time. A cyclist completing a lap has zero displacement, resulting in zero average velocity.

What is a key characteristic of velocity?

• It only has magnitude.

• It is measured in seconds.

• It is a scalar quantity.

• It has both magnitude and direction.

In which direction is the plane traveling?

• Northeast

• Northwest

• Southeast

• Southwest

How is average velocity calculated?

• By dividing distance by time

• By dividing displacement by time

• By adding speed and time

• By multiplying speed by time

What is the average velocity of a cyclist after completing one lap of a track?

• Equal to the speed of the cyclist

• Equal to the time taken

• Zero

• Equal to the distance covered

Which of the following is true about displacement in the context of average velocity?

• It is always less than distance.

• It can be zero even if distance is not.

• It is the same as distance.

• It is always greater than distance.
