Question

what is the main difference between the speed and the velocity of an object? a speed has no direction associated with it, while velocity has a specific direction. b speed has a direction associated with it, while velocity has no specific direction. c velocity is the change in distance over time, while speed is the change in velocity over time. d velocity is the changes in speed over time, while speed is the change in distance over time.

Explanation:

Speed is a scalar quantity, only indicating magnitude (how fast an object is moving). Velocity is a vector quantity, which includes both magnitude and direction of motion.

Answer:

A. Speed has no direction associated with it, while velocity has a specific direction
