What is the main difference between speed and velocity as described in the passage?

• Speed is a vector quantity, while velocity is a scalar quantity.

• Speed considers direction, while velocity does not.

• Velocity is a vector quantity, while speed is a scalar quantity.

• Velocity only measures how fast an object is moving.

How is average velocity calculated according to the passage?

• By dividing total displacement by total time taken.

• By adding initial and final velocities and dividing by two.

• By multiplying speed by time.

• By subtracting initial velocity from final velocity.

In the passage, what example is given to illustrate the concept of velocity?

• A car traveling 60 km to the east in one hour.

• A runner's velocity during a 5k race.

• The velocity of sound.

• The velocity of a bullet.

According to the passage, why is velocity considered a more comprehensive measure of motion than speed?

• Because it only measures the magnitude of movement.

• Because it includes both magnitude and direction of movement.

• Because it is easier to calculate than speed.

• Because it ignores the direction of movement.

What does the passage suggest about the applicability of velocity beyond physical movement?

• It is only applicable to physical objects.

• It can describe the rate of historical change and the velocity of money.

• It is not applicable to non-physical phenomena.

• It is only used in scientific analysis.
