Force

Calculate net force from mass and acceleration using Newton’s second law.

How this calculator works

Enter the values for first value, second value and review the units before calculating.

Formula / method

F = m × a

Worked example

A 10 kg mass accelerating at 9.81 m/s² experiences 98.1 N of net force.

Assumptions and limitations

Mass is inertial mass and acceleration is expressed in meters per second squared.

The result is net force; friction, drag and separate applied forces are not resolved.
