This video tutorial provides a breakdown of speed and velocity. Speed is defined as a scalar quantity that measures how fast an object is traveling, calculated by dividing distance by time. Velocity, on the other hand, is a vector quantity that includes both magnitude and direction, calculated by dividing displacement by time. The video uses examples to differentiate between speed and velocity, emphasizing that velocity provides directional information. It also explains how vector quantities can be represented using arrows, which is useful for operations like adding or subtracting velocities. The video concludes with a review of these concepts.
