Speed only tells how fast something is going, while velocity tells speed and direction.
when you know both speed and direction of an objects motion you know the velocity of an object.
Speed is a scalar quantity that describes how fast an object is moving regardless of its direction, while velocity is a vector quantity that describes both the speed and direction of an object's motion. Speed is expressed as a magnitude only, whereas velocity includes both magnitude and direction.
Velocity is speed with a direction
Velocity
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
VELOCITY
angular velocity
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.
Speed and direction is called velocity.
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
They have exactly the same size. The difference is that 'velocity' tells you which way the 'speed' is going.
