Which of the following best describes the velocity of an object?

• 50 m/s

• 50 m east

• 50 m/s east

• 50 m/s²

What is the difference between the velocity and the speed of an object?

• Velocity is the change in distance over time, while speed is the change in velocity over time.

• Velocity has a direction associated with it, while speed has no specific direction.

• Velocity has no direction associated with it, while speed has a specific direction.

• Velocity is the change in speed over time, while speed is the change in distance over time.

How does acceleration appear on a distance-time graph?

• As a curved line

• As a straight horizontal line

• As a straight vertical line
