Question

Explain why streets and highways have speed limits rather than velocity limits

Answer 1

Short Answer: Velocity is a speed with direction and speed on its own doesn’t have a direction.

Long Answer: They have speed limits rather than velocity limits is because velocity is considered a vector - a quantity that is fully deceived by both magnitude and direction (meaning that includes direction). On the other hand, speed is considered a scalar - a quantity that is fully described by magnitude alone (meaning there isn’t a direction)
