Average Velocity Calculator
Calculate average velocity using v_avg = (u + v) / 2
Average Velocity Calculator – Calculate Average Velocity Easily
An Average Velocity Calculator allows you to calculate the average velocity of an object when you know its initial velocity (u) and final velocity (v). Using the simple formula:
v_avg = (u + v) / 2
this calculator provides an instant solution, saving time and minimizing errors in motion analysis. This is especially useful for physics students, engineers, and anyone working with uniformly accelerated motion.
What Is Average Velocity?
Average velocity is the overall velocity of an object over a period of time. Unlike instantaneous velocity, which measures speed at a single moment, average velocity takes into account the initial and final velocities to provide a single representative value for the motion.
For uniformly accelerated motion (constant acceleration), the average velocity can be calculated directly as:
v_avg = (u + v) / 2
Where:
- u = initial velocity
- v = final velocity
- v_avg = average velocity
How to Find Initial or Final Velocity
If you know the average velocity and one of the velocities, you can calculate the missing value using these formulas:
- To find initial velocity:
u = 2 × v_avg − v - To find final velocity:
v = 2 × v_avg − u
These formulas are especially helpful when solving physics problems with uniform acceleration.
Average Velocity Example
Given:
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 20 m/s
Calculation:
v_avg = (u + v) / 2 = (10 + 20) / 2 = 15 m/s
Result:
The average velocity is 15 m/s.
Example 2: Finding Initial Velocity
Given:
- Average velocity (v_avg) = 15 m/s
- Final velocity (v) = 20 m/s
Calculation:
u = 2 × v_avg − v = 2 × 15 − 20 = 10 m/s
Example 3: Finding Final Velocity
Given:
- Average velocity (v_avg) = 15 m/s
- Initial velocity (u) = 10 m/s
Calculation:
v = 2 × v_avg − u = 2 × 15 − 10 = 20 m/s
Units for Average Velocity
- Meters per second (m/s) – Standard SI unit
- Kilometers per hour (km/h) – Common for vehicles
- Miles per hour (mph) – Used in some regions
Ensure both u and v are in the same units for accurate calculation.
