- The key difference between them is that velocity is a vector quantity that describes both how fast and in which direction an object is moving, while speed is a scalar quantity that describes only how fast an object is moving. Speed is the magnitude of the velocity vector.

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

Velocity is a vector quantitythat refers to "the rate at which an object changes its position." Imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. While this might result in a frenzy of activity, it would result in a zero velocity. Because the person always returns to the origi...
The task of describing the direction of the velocity vector is easy. The direction of the velocity vector is simply the same as the direction that an object is moving. It would not matter whether the object is speeding up or slowing down. If an object is moving rightwards, then its velocity is described as being rightwards. If an object is moving d...
In contrast, the average velocity is often computed using this formula Let's begin implementing our understanding of these formulas with the following problem: Q: While on vacation, Lisa Carr traveled a total distance of 440 miles. Her trip took 8 hours. What was her average speed? To compute her average speed, we simply divide the distance of trav...
Since a moving object often changes its speed during its motion, it is common to distinguish between the average speed and the instantaneous speed. The distinction is as follows. 1. Instantaneous Speed- the speed at any given instant in time. 2. Average Speed- the average of all instantaneous speeds; found simply by a distance/time ratio. You might...

Speed and velocity are related in much the same way that distance and displacement are related. Speed is a scalar and velocity is a vector. Speed gets the symbol v (italic) and velocity gets the symbol v (boldface). Average values get a bar over the symbol.
Speed is a scalar quantity with just concerning the magnitude and velocity is a vector quantity that must consider both magnitude and direction. SPEED. Speed can be defined as “how fast something moves” or it can be explained more scientifically as “the distance covered in a unit of time”.
In this section we will look at time, speed, and velocity to expand our understanding of motion. A description of how fast or slow an object moves is its speed. Speed is the rate at which an object changes its location. Like distance, speed is a scalar because it has a magnitude but not a direction.
