What is the difference between speed and velocity?

Velocity is the speed at which an object moves along a trajectory, while velocity is the speed and direction of an object's motion. In other words, velocity is a scalar value, while velocity is a vector. In conclusion, velocity and velocity are kinematic quantities that have distinctly different definitions. Velocity, being a scalar quantity, is the speed at which an object covers the distance.

Average velocity is distance (a scalar quantity) per time ratio. On the other hand, velocity is a vector quantity; it is aware of direction. Velocity is the speed at which the position changes. The average velocity is the displacement or change in position (a vector quantity) per time ratio.

Velocity is the rate of change of motion, that is, the distance traveled by an object in a specific time regardless of direction. Speed is speed with respect to direction. Velocity is a scalar quantity, while velocity is a vector. Velocity represents the speed at which the position of an object changes.

This is different from speed, which takes distance as a reference. The difference between displacement (change of position) and distance is essential to understand the concept of speed and its difference with respect to speed. The following image shows a journey from point A to point D. Joao Amadeu has more than 10 years of experience teaching physics and mathematics at different educational levels.

This lesson introduced the concepts of speed and speed, and pointed out the main differences between them. In physics, you can calculate the average speed by taking the total distance traveled and dividing it by the total time required to cover that distance. Average speed is generally used to estimate the amount of time it takes to cover a distance between specific points while driving. In other words, the total distance traveled divided by the total time interval is the average speed of the body.

The term instantaneous (velocity or velocity) refers to a quantity measured at a specific instant of time. To give it an official definition, speed is the distance traveled for a specific period of time, regardless of the direction traveled. Since an object in motion often changes its speed during its movement, it is common to distinguish between average velocity and instantaneous velocity. This was the case with speed.

Now, if I ask what directions I took on my trip and from the beginning, in the middle or when turning and until the end, was my speed the same? The answer will be clearly No, because initially, the speed was 0 when my car was at rest when I started, it was slow, I also increased my speed and also decreased it during corners; in general, my speed was not the same, which means that I traveled with a speed (variable speed) to cover 120 km of distance in 5 hours. Difference between distance and displacement: distance, which is a scalar quantity, refers to the total area covered by an object, while a displacement, which is a vector quantity, deals with the change in the position of the object. Keep in mind that velocity has no direction (it's a scalar) and velocity at any instant is simply the value of velocity with a direction. You can think of instantaneous speed as the speed that the speedometer reads at any given moment and average speed as the average of all the speedometer readings during the trip.

Compare this to an object that moves slowly and has a low speed; it covers a relatively small amount of distance in the same amount of time. Although both provide similar information about the movement of a body, they are different types of quantities. Speed is the distance traveled for a specific period of time, regardless of the direction traveled.
