Explanation:
Detailed explanation-1: -Velocity is called as speed in a specified direction. Velocity tells us how fast or slow an object is moving in a specified direction.
Detailed explanation-2: -Speed tells you only how fast or slow an object is moving. It doesn’t tell you the direction the object is moving. The measure of both speed and direction is called velocity. Velocity is a vector. A vector is measurement that includes both size and direction.
Detailed explanation-3: -The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).
