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.

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

Explanation:

The speed of an object is the distance covered by the object within a certain period. It is a measure of distance traveled by the object per time.

The velocity of an object is the speed of the object when moving in a specified direction.

For example, a car speeding at 50 km/hr has a speed of 50 km/hr but no one knows which direction it is heading. A car speeding at 50 km/hr in the NorthEast direction has a velocity of 50 km/hr in the NE direction.

Speed is scalar quantity, that is, it has magnitude but no direction. Velocity on the other hand, is a vector quantity because it represents speed with direction.

The second option is the correct answer. That is, "Velocity has a direction associated with it, while speed has no specific direction."
