How to Calculate Velocity

The formula for velocity around a circle is v = (2 * pi * r) / t, where 'r' is the radius and 't' is time. For an object moving around a circle with a radius of 50 meters in 13 seconds, the velocity is approximately 24.17 meters per second.

Velocity is the speed an object travels in a given direction. The most basic formula is velocity (v) = distance (d) / time (t). To find distance, subtract the initial position from the final position. To find time, subtract the start time from the end time.

For a runner going from 22 meters to 52 meters in 5 seconds (5:35:01 PM to 5:35:06 PM), the distance is 30 meters and the time is 5 seconds. This results in an average velocity of 6 meters per second east.

For accelerating objects, if you know the acceleration rate, the final velocity (vf) = initial velocity (v1) + (acceleration (a) * time (t)). For example, if an object accelerates north at 5 m/s² for 5 seconds with a starting velocity of 6 m/s, its final velocity is 31 m/s north.

To find the average velocity of an accelerating object, add the initial velocity to the final velocity and divide by two. Using the previous example, (6 m/s + 31 m/s) / 2 = 18 m/s north.
