# What is the Difference Between Speed and Velocity?

Do you want to know the difference between speed and velocity? If so, you are in the right place at the right time…!!!

The reason is straightforward. Speed is the rate at which an object moves along a path in time, whereas velocity is the rate and direction of movement. In other words, velocity is a vector, whereas speed is a scalar value.

The primary distinction between speed and velocity is that speed defines how quickly an object moves, whereas velocity defines how quickly an object moves but in which direction. As a result, speed is a scalar quantity, whereas velocity is a vector quantity.

Not to mention that both are used to specify the movement of an object between two points. They are, however, diametrically opposed. Or, perhaps, almost…!!!

In this exclusive article, we will discuss a variety of speed and velocity differences. In fact, we’ll discuss some of the similarities between them. But first, let me give you a quick overview of the two in a table format. Let’s get started…!!!

Try to Understand:

## Speed vs Velocity

From the above difference between speed and velocity in tabular form, you got the exact overview of these two. However, in order to get to know them, let us try to understand both of them in a detailed format. Keep reading!

## What is Speed?

Speed is defined as the rate of change of distance covered by an object per unit of time. In other words, speed is the rate at which an object moves along a path in time.

In other words, there is no need to consider an object’s motion direction when defining speed. As a result, speed is a scalar quantity. That is, it has magnitude but no direction.

A Bugatti Veyron travelling at 160 m/s, for example, could easily go from 0 m/s to 100 m/s before reaching 140 m/s and even 180 m/s. The average speed, however, will always be the speed of the Bugatti Veyron.

Not to mention that the SI unit of speed is meters per second. An object’s true speed can never be zero. Furthermore, because the SI unit of speed is m/s, the speed dimension is LT-1.

### Properties of Speed

There can be so many properties of speed. Some of them are listed below:

• Speed is a scalar quantity.
• Speed is path-dependent.
• The magnitude of speed is always positive.
• Speed is always symmetric, etc.

## What is Velocity?

Velocity is defined as the rate of change of displacement covered by an object per unit time. In other words, velocity is both the rate of change of time and the direction of motion of a moving object.

In other words, in order to define velocity, we must consider the direction of an object’s motion. As a result, velocity is a vector quantity. That is, it has both magnitude and direction.

A high-speed bullet train, for example, travels at an average speed of 150 km/h. However, it will have a southward velocity of 150 km/h.

Not to mention that the SI unit of velocity is meters per second. An object’s velocity can be negative, positive, or even zero. Furthermore, because the SI unit of velocity is m/s, the velocity dimension is LT-1.

### Properties of Velocity

There can be so many properties of velocity. Some of them are listed below:

• Velocity is a vector quantity.
• Velocity is path-independent.
• The magnitude of velocity can be negative, positive, or, zero.
• Velocity is anti-symmetric, etc.
