Overview

Calculate force, mass, or acceleration using Newton's Second Law (F = ma). Used in mechanics problem-solving, structural design, vehicle dynamics, and various physics and engineering applications.

Formula

Force = Mass × Acceleration  (F = m × a)
Mass = Force ÷ Acceleration  (m = F / a)
Acceleration = Force ÷ Mass  (a = F / m)

Weight = Mass × Gravitational Acceleration  (W = m × g, g ≈ 9.8 m/s²)

Units: Force (N, Newton), Mass (kg), Acceleration (m/s²)

How to Use

1. 1Select the value to calculate (force, mass, or acceleration).
2. 2Enter the other two known values.
3. 3Verify units (N, kg, m/s²).
4. 4Click calculate to view the result.

Tips

• ✔1 N is the force needed to accelerate 1 kg at 1 m/s².
• ✔Weight is F = mg; a 1 kg object weighs approximately 9.8 N on Earth.
• ✔When multiple forces act on an object, calculate the net (resultant) force.
• ✔Friction force = coefficient of friction × normal force (f = μN).
