Acceleration Calculator
Find acceleration from initial velocity, final velocity, and time.
Acceleration
4 m/s²
Enter the initial and final velocity along with the elapsed time to compute average acceleration using a = (v_f − v_i) / t.
How to use
- Enter the initial velocity in meters per second.
- Enter the final velocity and the elapsed time.
- Read the acceleration below.
Frequently asked questions
- How is acceleration calculated?
- Acceleration = (final velocity − initial velocity) / time. It measures how fast velocity changes.
- Can acceleration be negative?
- Yes. A negative value means the object is slowing down (deceleration) relative to its direction of motion.
