Which is an example of speed?

Speed is a scalar quantity, so you can probably guess that speed has a corresponding vector quantity that combines how fast an object is traveling and its direction of travel. This vector quantity is velocity, defined as the rate at which an object changes position. read more

Speed is a scalar quantity while Velocity is a vector quantity: Speed: I am driving my car at 100 km/hr. Velocity: I am driving my car at 100 km/hr in the south-south-east direction (SSE). Speed is just a scalar magnitude value, while Velocity includes the scalar magnitude plus a direction. The same is true for forces and accelerations for example. read more
