Final Velocity Calculator (v = u + at)
Final Velocity Calculator (v = u + at)
This is the first SUVAT equation of motion, relating final velocity to initial velocity, acceleration, and time. Choose which variable to solve for, enter the other three, and this calculator computes the answer.
This is the simplest of the three SUVAT equations since it involves only velocity, acceleration, and time — no displacement at all — which makes it the natural first step in a physics problem where distance covered isn't yet known or isn't relevant to the question being asked. Once you know the final velocity, the related Displacement Calculator (using the second SUVAT equation) is the natural next tool if the problem also asks how far the object traveled during that same interval.
- v = u + at, so starting from rest (u = 0) and accelerating at 5 m/s² for 4 s gives a final velocity of 0 + 5×4 = 20 m/s.
- This is the simplest of the three SUVAT equations since it doesn't involve displacement at all - just velocity, acceleration, and time.
- See the Displacement Calculator for the position (s = ut + ½at²) that results from the same initial velocity, acceleration, and time.
How do I calculate final velocity?
Add the product of acceleration and time to the initial velocity: v = u + at.
What is the final velocity after accelerating from rest at 5 m/s² for 4 seconds?
v = 0 + (5 × 4) = 20 m/s.
