Average velocity

displacement vector / time

Average velocity is the measure of displacement over a given time period. To calculate average velocity, you need to know the initial position (x1), the final position (x2), and the time it took to go from x1 to x2 (t).

The formula for average velocity is:

Average velocity = (x2 - x1) / t

Here's an example to help demonstrate how to calculate average velocity:

Let's say a car starts at position x1 = 10 meters and travels to position x2 = 50 meters in a time of t = 5 seconds. Using the formula, we can calculate the average velocity as follows:

Average velocity = (50 - 10) / 5
= 40 / 5
= 8 meters per second

So, the car's average velocity is 8 meters per second. Meaning, on average, it traveled 8 meters each second during that time.

Remember, average velocity is a vector quantity, meaning it has both magnitude and direction. So, if the direction of the car's motion changes, you'll need to consider both distance and direction when calculating average velocity.
