Force Calculator (F = ma)

Enter any two of Force, Mass, or Acceleration — the third is calculated using Newton's Second Law.

Formula used

F = m × a

Force (F): 50 N

Mass (m): 10 kg

Acceleration (a): 5 m/s²

Force equivalent ≈ 5.0985810649 kgf (kilogram-force)

Newton's Second Law: F = m × a  |  1 N = force to accelerate 1 kg at 1 m/s²
