Frequently Asked Questions

What is Newton's second law of motion?

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula is F = m × a, where F is force, m is mass, and a is acceleration.

What units should I use?

For accurate results, use standard units: force in newtons (N), mass in kilograms (kg), and acceleration in meters per second squared (m/s²).

Can I use this calculator on my phone?

Yes! Our calculator is fully responsive and works perfectly on all devices including smartphones, tablets, and desktop computers.

Is this tool completely free?

Absolutely! This is a free online physics calculator with no hidden costs, registration requirements, or usage limits.
