The motion of an object can only be described by determining how fast or how slow it moves. The measure of how fast something is moving is known as speed. Speed is the rate at which distance is covered at a given time. Learn more about Speed
Formula:
VELOCITY
Velocity is the rate at which an object changes its position. It is a vector quantity. The direction of velocity is the direction in which the object is moving. The absolute value or the magnitude of velocity is speed. Velocity can also be defined as the displacement of an object in a specified direction. If the object returns to its starting point then its velocity is zero. Learn more about Velocity
Formula:
SPEED vs VELOCITY
The difference between speed and velocity is that speed is a scalar quantity whereas velocity is a vector quantity.
From the definition of velocity, it follows that, to have a constant velocity, both speed and direction must be constant. Motion at constant velocity is motion in a straight line at uniform speed.
