How to use: Choose velocity input mode using the buttons. In "Direct Δv" mode, enter any 2 out of 3 values (a, Δv, t) and the third will be calculated. In "Initial & Final" mode, enter any 3 out of 4 values (a, v₀, v, t) and the fourth will be calculated. The calculator automatically determines velocity change (Δv = v - v₀) when using initial and final velocities. All unit conversions are handled automatically.
Example: 9.8 for gravity, 3.5 for car acceleration
Velocity Input Mode
Example: 25 for speed increase from 0 to 25 m/s
Example: 0 for starting from rest, 20 for moving object
Example: 30 for final speed after acceleration
Example: 5.5 for five and half seconds

Physics Acceleration Calculator
This acceleration calculator helps you determine acceleration, velocity change, or time using the fundamental physics formula. The calculator supports multiple unit systems and provides two convenient input modes for different calculation scenarios.
a = Δv / t
where Δv = v - v₀
a = acceleration (m/s², ft/s², etc.)
Δv = velocity change (m/s, mph, km/h, etc.)
v = final velocity
v₀ = initial velocity
t = time (seconds, minutes, hours, etc.)
Two Calculation Modes
Direct Δv Mode
Enter any 2 of 3 values: acceleration (a), velocity change (Δv), and time (t). The calculator will determine the missing value using the direct formula.
Initial & Final Mode
Enter any 3 of 4 values: acceleration (a), initial velocity (v₀), final velocity (v), and time (t). The calculator automatically computes velocity change.
Example Calculation:
A car accelerates from rest (v₀ = 0 m/s) to 30 m/s in 6 seconds. The acceleration is:
a = Δv / t = (30 - 0) / 6 = 5 m/s²
