Net force98.1 N

Method, variables and units

Force Calculator

Formula: F = m x a

  • F — force (N)
  • m — mass (kg)
  • a — acceleration (m/s^2)

Assumption: The calculation uses Newton's second law for net force in an inertial frame.

Worked example

Force Calculator

A 10 kg object accelerating at 9.81 m/s^2 has a net force of 98.1 N.

Important limits
