Average Acceleration
Acceleration measures how velocity changes over time and can be signed in one dimension.

How to use this calculator
- Enter initial velocity in m/s.
- Enter final velocity in m/s.
- Enter elapsed time in s.
- Select Calculate and keep the output unit with the answer.
Before you use the answer
Choose a system boundary and a positive direction before entering measured values. Introductory equations deliberately leave out some real-world effects. If the setup has changing acceleration, drag, losses or nonuniform properties, first decide whether the simplified model is a useful approximation.
This is average acceleration. The instantaneous value may vary during the interval.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
