Force, mass and acceleration
Solve Newton’s F = ma for one missing quantity in SI units.
Select the unknown and enter the other two quantities. The tool uses F = ma or its rearrangement, returning force in newtons, acceleration in m/s² or mass in kilograms.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
Solve for: force Mass (kg): 2 Acceleration (m/s²): 3 Force (N): 6
Example result
{
"newtons": 6
}Limitations and details
Mass must be positive and mass-solving requires nonzero acceleration; this is a scalar classical model without vector components.
