Acceleration Calculator (Newton's Second Law)

Solves a = F / m using Newton's second law, and rearranges to find force or mass when you have the other two. It also converts force into lbf, kgf, and dyne and reports acceleration in g-units.

How to use
  1. Choose whether to solve for acceleration, force, or mass.
  2. Enter the two known values with their units.
  3. Check the g-unit output for a quick intuition.
Examples
Acceleration
10 m/s²

F / m = 100 / 10

For study and estimation. Verify against authoritative data before relying on a result.

Common questions

What is Newton's second law?

Force equals mass times acceleration, F = ma. Rearranged, acceleration is force divided by mass.

How do I express acceleration in g?

Divide the acceleration in m/s² by 9.81. The tool does this automatically so you can compare against the pull of gravity.
