How it works
The formula behind this calculator.
F = m × a (net force = mass × acceleration)
- F
- Net force (N)
- m
- Mass (kg)
- a
- Acceleration (m/s²)
Newton's 2nd law. The net force (sum of all forces) equals mass times acceleration. 1 N = 1 kg·m/s².
Example: 10 N on 2 kg → 5 m/s² acceleration
Ref: Newton (1687), Principia
Tips
- 💡 F = m × a. The net force, not just one force. Always sum forces before applying F = ma.
- 💡 Mass is in kg, force in newtons (N). 1 N = 1 kg·m/s².
