Force – Mass – Acceleration (F = m·a) Calculator

Calculates force, mass, or acceleration using F = m·a.

Info

This tool uses Newton's 2nd Law, F = m·a, to find the unknown among force (F), mass (m), and acceleration (a). Core formulas: - F = m · a (force) - m = F / a (mass) - a = F / m (acceleration) Units: - F (force): Newton (N) - m (mass): kilogram (kg) - a (acceleration): m/s²

Newton's 2nd Law – F = m·a

Force equals mass times acceleration: F = m·a.
With constant mass, as force increases, acceleration increases (direct proportion).
Under the same force, as mass increases, acceleration decreases (inverse proportion).
SI units: F [N], m [kg], a [m/s²].

This tool performs a basic F = m·a calculation for linear, one-dimensional, net force scenarios. Real-world effects such as friction and air resistance are not considered.
