Velocity is the speed with a direction. It is also described as the change in position over the change in time. **Velocity** is the rate at which displacement changes with time. Here is **how to Calculate Velocity**.

## How to Find the Simple Velocity

- Write down
**the Velocity Formula**. **Plug the values**into the formula.**Example:**John walks from his home to school in 6 minutes and 40 seconds, what is his velocity?**Displacement**= 200 m And**Time**= 6 minutes and 40 seconds = 400 s**Velocity**= North-West =**0.50 m/s**North-west

## How to Find Average Velocity

- Write the formula for
**Average Velocity.** - Find
**the distance between the start and end points.** **Subtract the start time from the end time**to find out the change in time.- To find out the average velocity,
**divide the total displacement by the total time.**

**Example: **A car traveling due east starts at position x = 0 meters. After 8 seconds, the car is at position x = 72 meters. What was the car’s displacement?

## How to Find Average Velocity when Acceleration is Constant

- Write the formula for
**Average Velocity if acceleration is constant**.
