Acceleration Calculator (Uniform Motion)

Find the acceleration of uniformly accelerated linear motion from initial velocity, final velocity, and time. Also shows distance and average velocity.

Input

For uniformly accelerated linear motion, enter the initial velocity, final velocity, and elapsed time to compute the acceleration.

Initial velocity v0

m/s

Final velocity v

m/s

Elapsed time t

Acceleration is found from a equals (v minus v0) divided by t. Enter all values in SI units (m/s and s).

Result

Acceleration a

6m/s²

Speeding up (velocity increases)

Distance s

75 m

Average velocity

15 m/s

Velocity change v minus v0

30 m/s

In uniform acceleration the velocity changes linearly with time, its slope is the acceleration, and the area below the line is the distance traveled.

How it works

Acceleration is computed as a equals (v minus v0) divided by t, where v0 is initial velocity, v is final velocity, and t is elapsed time.
Average velocity is (v0 plus v) divided by 2, and distance is (v0 plus v) divided by 2 times t for uniform acceleration.
Units follow the SI base system: velocity in m/s, time in s, and acceleration in m/s squared.
A negative acceleration means deceleration, where the speed decreases.
Time t must be a positive value. Acceleration is undefined when t is zero or less.
