Speed is determined by the rate of changes of movement, or the distance travelled by a body in a given period independent of direction, while velocity is the speed of direction. Velocity is a vector, while speed is a scalar quantity.
Here are some of the main differences between speed and velocity to help you understand how both differ:
Speed Vs Velocity:
Speed:
The amount at which an object travels a certain distance is referred to as its speed.
It is a scalar quantity in the notion that orientation is not required to predict speed.
If an item travels no distance, its speed is 0.
The speed at any given moment is referred to as instantaneous speed.
The average speed is the sum of all instantaneous speeds or distance per time ratios.
Velocity:
The amount at which an item changes position is defined as its velocity.
It is a vector quantity.
The direction of velocity is the direction in which the item is moving.
Speed is defined as the absolute value or magnitude of velocity.
Velocity may also be described as an object’s displacement in a certain direction.
What is the Difference between Speed and Velocity?
Speed is the rate at which a body travels along a path in time, while velocity is the rate and direction of an object’s position.
So, what’s the difference? Let’s discuss the difference between speed and velocity:
| Velocity | Speed |
| The pace at which an item changes position in a particular direction is described as velocity. | The amount at which an item travels a given distance is referred to as its speed. |
| The vector quantity. | The scalar quantity. |
| The magnitude of velocity might be negative, positive, or zero. | There can never be a negative or zero speed. |
| Because the velocity of the item changes with direction, the object must only go in one direction. | Unless the object changes direction, the average speed is still computed. |
| An item may have many velocities yet the same speed. | Speed and velocity are not always equal. |
| The velocity is measured in meters per second. | The speed is measured in meters per second (m/s). |
| v = x/t; where is the average velocity, ‘t’ is the arrival time, and ‘x’ is the displacement | v = d/t, where ‘v’ represents the average speed, ‘t’ represents the time necessary to complete the distance, and ‘d’ represents the total distance travelled. |
| For example, A train heading south at an average speed of 50 km/h, for illustration, will have a north velocity of 50 km/h. The velocity of a straight object travelling in a specific direction is defined. | For example, A 50 m/s sports bike would travel from 0 to 30 m/s before reaching 50 m/s and may potentially reach 70 m/s. Therefore, the average speed will equal the bike’s speed. |
Conclusion:
After reading this article you learned a lot about the differences between speed and velocity, they are no longer able to confuse you.
When driving, the average speed is typically used to determine the amount of time required to travel a distance between certain sites. A speedometer indicates the current speed of a vehicle.
The time it takes a hurricane to reach the coast, rockets to reach the moon, and so on is determined by velocity.
