F
Force Calculator
Newton’s second law: find the force, the mass or the acceleration from the other two.

How it's calculated
F = m × a m = F ÷ a a = F ÷ m
Force is mass times acceleration, measured in newtons (kg·m/s²). Use the net force: if friction or drag pushes back, the acceleration comes from what is left over. Weight is the same law with a = g, so a 1 kg mass weighs about 9.81 N on Earth.
