The velocity of any item is defined as the rate of change in the location of the object relative time combined with its direction. Average velocity is the displacement of the item to time, it is also called the change in the position of the object divided by the time frame. Instantaneous velocity is the rate of displacement or rate of change in position to time at a certain location.

## Average Velocity Vs. Instantaneous Velocity

The distinction between Average Velocity and Instantaneous Velocity is because they vary in their formula, their attitude towards acceleration, and their values. They share and vary in a number of ways. Both average velocity and instantaneous velocity are vector quantities and have the same SI units.

Average Velocity is the ratio of displacement to the time needed for such displacement to occur. It is a vector quantity. The sole difference between an average speed and average velocity is that average speed is determined by dividing the rate of distance traveled by time, while average velocity is derived by dividing the rate of displacement by time elapsed.

Instantaneous velocity is defined as velocity or displacement at a moment of time. Average velocity and instantaneous velocity will approach unity when the velocity is constant or the acceleration is zero. It is a vector quantity and its SI unit is meter per second which is the same as average velocity.

## What is Average Velocity?

Average velocity is a number that is presented about time. It is the rate of change in location or displacement during a specific time between the locations of the item being moved. It is computed as the rate of displacement divided by time elapsed. It is a vector quantity. A meter per second is the metric unit for this speed.

Average velocity comprised both magnitude and direction, unlike average speed which included simply the magnitude. The fluctuating velocity of an item aids in estimating the entire travel of the object using average velocity. It may be obtained as total displacement divided by the entire time taken.

Average velocity may be computed using a total velocity divided by time. When the item has varied velocity during its trip then average velocity may be determined as the total of all its displacements divided by the amount of time taken. It is also called Average Linear Velocity.

When an item is travelling in a straight line towards a given direction, its average velocity may be measured using average linear velocity, however when an object circles around a circular direction and reaches a certain point, it is termed Average Angular Velocity.

## What is Instantaneous Velocity?

Instantaneous velocity is the number that represents the speed of an item coupled with its direction between two places. It is the velocity between two places at one moment of time. It has a restriction that the time between the two pints or the time passed during the displacement approaches zero.

Instantaneous velocity has the SI unit as a meter per second or CGS unit as length per time. It is a vector quantity that represents both the magnitude and speed of an item over time. Instantaneous velocity may be negative or positive, however Instantaneous speed is always positive which is obtained using instantaneous velocity.

Instantaneous velocity may be represented using graphs and slopes. When the acceleration is 0 or the velocity is constant throughout time, it is equal to the average velocity. It is the velocity at every moment of time, a graph that depicts velocity at every instant of time is also known as instantaneous velocity.

A graph drawn using the position of the location of the item vs the time frame, such that the slope thus occurring is the tangent line and therefore the resultant velocity is said to be Instantaneous velocity. Instantaneous velocity and instantaneous speed are the same except they vary in their vector and scalar values.

## Difference Between Average Velocity and Instantaneous Velocity

- Average velocity is the rate of movement divided by time elapsed, while Instantaneous velocity is the velocity at a moment in a time frame of an object.
- When time approaches zero, average velocity equals instantaneous velocity, and when acceleration is zero, instantaneous velocity equals average velocity.
- It is possible to think about average velocity as a vector. Instantaneous velocity may be thought of as another kind of vector quantity.
- The unit of measure for average velocity is the meter per second, whereas the measure for instantaneous velocity is the length per unit of measurement.
- If the average velocity is displayed across many time periods, we may get an idea of the instantaneous velocity.

## Conclusion

An object’s average velocity is its average speed between any two points in time. The difference in distance between two places on an item at a given moment in time is known as the object’s instantaneous velocity. The values and units are identical to those of vectors. Graphs and slopes are used to illustrate and explain both Average and Instantaneous Velocity.

When an item goes in a straight line, it is known as Average Linear Velocity; when it moves in a circular route, it is known as Average Angular Velocity. These variances are not present in Instantaneous Velocity, on the other hand. Instantaneous speed may be produced using Instantaneous velocity.
