How is speed and velocity different?
Velocity has a direction.

Speed is a scalar and velocity is a vector (has a direction). Speed can be said to be omni-directional like the speed of light.
A speed is a measurement like "20 meters/second" or "72 kilometers/hour", without a specification of a direction. When direction is important (e.g., "20 meters/second to the n…orth"), then the measurement is called a velocity.
Velocity is a vector quantity, which means that a body's speed and direction are both required to define it.. They are different because: Speed is the rate of change of dist…ance with time but velocity is the rate of change of displacement with time.
Speed is the distance an object travels per unit of time and velocity describes the speed and direction of a moving object.
As used in physics, velocity is a vector, that is to say, the direction of the movement is also taken in account.
Velocity is a vector, meaning that it has a direction. When it is being expressed, the direction is given with it (e.g. 5m/s NW). Speed is a scalar, not a vector, so it doe…sn't have a direction connected with it. Thus, when it is expressed, the direction variable is omitted (e.g. 5m/s). Acceleration is a change in velocity or speed over time. It will be a vector when it is referring to a change in velocty (e.g. 10m/s 2 SE), and it will be a scaler when it is referring to a change in speed (e.g. 10m/s 2 ).
Speed is the rate of covering distance. 60 mph north, south, or west are all exactly the same speed. Velocity is speed and its direction. 60 mph north, south, and east ar…e three different velocities.
Speed and velocity both measure an object's change in position per unit time, but velocity also depends upon the object's direction of motion.
Speed is a scalar quantity and only refers to how fast an object is moving. Velocity is a vector quantity and also takes into account direction.
Speed does not have the direction associated with it, like velocity does.
Velocity has a DIRECTION as well as a MAGNITUDE (that is, velocity is a VECTOR quantity if you've learnt that term yet) The magnitude of velocity is called SPEED (just a POSIT…IVE number/scalar, not a vector)
Speed is the magnitude of velocity (which has a direction as well).
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" areiden…tical speeds but different velocities.
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Ve…locity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
Velocity is speed with direction
Speed is a scalar magnitude (it only tells you how much). Velocityis composed of the object's speed and the direction in which it'smoving. This corresponds to the definition o…f a vector. Using "miles" and "hours" as an example: . "30 miles per hour (mph) " is a speed . "30 miles per hour (mph) north" is a velocity . "30 mph north" and "30 mph east" are different velocities withthe same speed. . "30 mph north" and "35 mph north" are differentvelocities/speeds with the same direction. . If you add "30 mph" plus "30 mph", you get 60 mph ... maybe. . If you add "30 mph north" plus "30 mph south", you get standingstill. . If you add "30 mph north" plus "30 mph east", you get 42.426mph northeast, using vector calculations. . Therefore, when a vehicle travels on a winding road maintaining aspeed of 30 mph, its speed remains the same but its velocity ischanging with each turn..
