Question:
The difference between speed and velocity is that
A) speed is a vector and requires a direction.
B) speed is a vector and requires a magnitude.
C) velocity is a vector and requires a direction.
D) velocity is a vector and requires a magnitude.
A) speed is a vector and requires a direction.
B) speed is a vector and requires a magnitude.
C) velocity is a vector and requires a direction.
D) velocity is a vector and requires a magnitude.
Answers
Answer: C) velocity is a vector and requires a direction. Explanation:In physics, there are two types of quantities:- scalars: these are quantities that have only a magnitude- vectors: there are quantities that have both magnitude and directionAs an example, speed is a scalar while velocity is a vector. Therefore, speed has only a magnitude, while velocity has both magnitude and direction: therefore, the difference between the two quantities is that velocity is a vector and requires a direction, as stated in option C.
Answer: velocity is a vector and requires a direction. Explanation:Speed is defined as the total distance covered per unit time and the velocity is defined as the total displacement per unit time.Speed is a scalar quantity and velocity is a vector quantity. The quantities that have both magnitude and direction are vector quantity and the quantity that have only magnitude are scalar quantity.The SI unit of both velocity and speed is m/s.So, the correct option is (c) " velocity is a vector and requires a direction ".
