📈 Acceleration Calculator
Calculate acceleration from velocity or force
How Acceleration Calculation Works
Formula
a = (v - u) / t or a = F / m
- 1Choose kinematics mode (a = (v-u)/t) or force mode (a = F/m).
- 2In kinematics mode, enter initial velocity, final velocity, and time.
- 3The change in velocity is divided by the time interval.
- 4In force mode, enter force and mass to find acceleration.
- 5Positive values indicate speeding up; negative values indicate deceleration.

Frequently Asked Questions
What are the units of acceleration?
The SI unit is meters per second squared (m/s²). This means the velocity changes by that many m/s every second. Earth's gravitational acceleration is 9.81 m/s².
Can acceleration be negative?
Yes, negative acceleration (deceleration) means the object is slowing down in the positive direction. For example, a car braking from 30 m/s to 0 in 10 seconds has an acceleration of -3 m/s².
What is the acceleration due to gravity?
On Earth, objects in free fall accelerate at approximately 9.81 m/s² (often rounded to 10 m/s²). This value varies slightly by location and altitude.
