What is the difference between speed and velocity?
a
Velocity has time.
b
Velocity has distance.
c
Velocity has weight.
d
Velocity has direction.
d) Velocity has direction.
Speed is a scalar quantity that refers to "how fast an object is moving." It is calculated as the distance covered per unit of time and does not take into account the direction of motion.
Velocity, on the other hand, is a vector quantity that refers to "the rate at which an object changes its position." It is calculated as the displacement per unit of time and includes both the magnitude and direction of motion. Therefore, velocity is speed with a specified direction.
