Speed is the rate at which an object changes its position. It is measured in units of distance per unit of time, such as meters per second (m/s) or kilometers per hour (km/h).
Direction is the orientation of an object's motion. It is measured in units of degrees, with 0 degrees representing the positive x-axis and 90 degrees representing the positive y-axis.
An object's velocity is a vector quantity, which means that it has both magnitude (speed) and direction. The magnitude of an object's velocity is the speed at which it is moving, and the direction of its velocity is the direction in which it is moving.
