Force Calculator
Find force from mass and acceleration (Newton's second law).
Newton's second law relates the force on an object to its mass and acceleration.
The math behind it
F = m × a. Force is in newtons (N) when mass is in kg and acceleration in m/s². Earth's gravity ≈ 9.81 m/s².
Worked example
10 kg × 9.81 m/s² = 98.1 N (the weight of a 10 kg object).
FAQ
What is 1 newton?
