Acceleration Calculator
Acceleration from initial and final velocity over time.

Formula: a = (v − u) / t
Worth Knowing
Acceleration is the rate at which velocity changes, and crucially it happens whenever speed OR direction changes — a car rounding a bend at constant speed is still accelerating, because its direction is turning. This is why you feel pushed sideways in a fast corner. A negative value simply means slowing down (deceleration). Acceleration is what you physically feel, not speed itself: cruising at highway speed feels like nothing, but the change getting there presses you into the seat.
How to Use
- Enter Initial velocity into the first field of the Acceleration Calculator.
- Fill in the rest: Final velocity, Time.
