Definition of Velocity
Velocity is a vector quantity that is used to measure the speed of an object together with the direction of an object. Velocity is one of the most significant qualities of a moving object.
Velocity of the body is defined as the rate of change in displacement of the body with time. It is also defined as the pace of an object in a certain direction.
Velocity Formula
Velocity is a vector quantity, i.e., it has both magnitude (speed) and direction. It is measured by the formula:
velocity = Displacement/Time
Unit of Velocity
Unit of velocity is meter per second or m/s. It is defined as the ratio of a unit of distance and a unit of time. Velocity is the measure of the speed of an object in a particular direction.
Although the unit of speed and velocity are identical, velocity, being a vector quantity, is defined as the rate at which an object changes its location per unit time. The other unit of velocity are km/hr, cm/s, ft/s, etc.
In this article, we will learn about velocity, units of velocity in different systems, SI Unit of velocity and will solve a few problems based on velocity.
