Force Calculator
Find a net force component from constant mass and signed acceleration in an inertial frame.
Formula
Fnet = ma; kg × m/s² = N.
Mass: 2 kg · Net force component ≈ (2 kg)×(3)
How to use
- Enter the object’s mass.
- Enter acceleration along your chosen axis.
- Read the net force component.
Examples
- A 0.5 kg mass accelerating at −4 m/s² has net force −2 N.
Frequently asked questions
Is this every individual force?
No. It gives the sum of forces along the axis.
What does a negative force mean?
The net force acts in the negative direction of the chosen axis.
When is F = ma appropriate?
For constant mass in classical mechanics and an inertial reference frame.
