Question

What is velocity and what are their types

Answer 1

The rate of motion of an object can be more comprehensive if we specify its direction and motion along with its speed. The quantity which specifies both these aspects is called Velocity.

Answer 2

A physics term, velocity describes the motion of objects. Velocity measures the movement of objects based on their speed and direction. The speed of an object measures how much distance it covers over a specific period of time. Speed is a scalar measurement since it only defines the magnitude of how fast an object is moving. Velocity is a vector quantity since it describes both speed and direction.
Types of velocity-
Constant Velocity
Changing Velocity
Mathematics of acceleration
Instant velocity
Terminal Velocity
