Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.
Speed only tells how fast something is going, while velocity tells speed and direction.
Its called VELOCITY.
Velocity also includes direction.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Velocity
Velocity.
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
when you know both speed and direction of an objects motion you know the velocity of an object.
angular velocity
accleration is the speed. Velocity is when you know the speed of an object and its direction.
Speed and direction is called velocity.
speed How fast in which direction is velocity.
