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
