Acceleration measures how quickly velocity changes — speeding up, slowing down, or changing direction.
Acceleration measures how quickly velocity changes — speeding up, slowing down, or changing direction. This calculator finds the average acceleration from the initial and final velocities and the time it took to change.
A car speeds up from 10 m/s to 30 m/s in 5 seconds. Acceleration = (30 − 10) / 5 = 4 m/s².
Acceleration = (final velocity − initial velocity) ÷ time, giving the rate at which velocity changes, typically in m/s².
Yes — a negative result means the object is slowing down (decelerating) rather than speeding up.
Use consistent units for velocity (e.g. m/s) and time (seconds) to get acceleration in m/s²; the calculator will convert common unit choices automatically if offered.
