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
