Force, Mass and Acceleration Calculator
Apply Newton's second law (F = ma) to calculate force, mass or acceleration for one-dimensional translational motion, with worked steps and a printable report. Runs locally in your browser.
Force, Mass and Acceleration Calculator
Newton's Second Law — F = ma. Select two known quantities to calculate the third for one-dimensional translational motion.
Positive and negative values represent opposite directions along one chosen axis. You must decide which direction is positive.
Calculation setup
Results
Enter both values for the selected known pair to see a result.

Formula
F = m × a
m = F ÷ a
a = F ÷ m (selected)
Newton's second law relates net force, mass and acceleration for one-dimensional translational motion with constant mass.

Assumptions and limitations
This calculator applies Newton's second law to idealised one-dimensional translational motion. It assumes constant mass and uses net force. It does not calculate resultant forces, friction, drag, rotational motion, changing-mass systems or multidimensional vectors. Signed values require you to define a positive direction. Results are informational and should be independently verified for professional or safety-critical engineering work. Force means net force: if multiple forces act on the object, combine them into a single net force before entering a value here. Mass is not weight. Standard gravity g₀ is an exact conversion constant, not a location-specific gravity model. No local gravitational variation is modelled. No structural integrity or compliance assessment is performed.
